The `node:dns` module enables name resolution. For example, use it to look up IP
addresses of host names.
Although named for the [Domain Name System (DNS)][], it does not always use the
DNS protocol for lookups. [`dns.lookup()`][] uses the operating system
facilities to perform name resolution. It may not need to perform any network
communication. To perform name resolution the way other applications on the same
system do, use [`dns.lookup()`][].
```mjs
import dns from 'node:dns';
dns.lookup('example.org', (err, address, family) => {
console.log('address: %j family: IPv%s', address, family);
});
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6
```
```cjs
const dns = require('node:dns');
dns.lookup('example.org', (err, address, family) => {
console.log('address: %j family: IPv%s', address, family);
});
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6
```
All other functions in the `node:dns` module connect to an actual DNS server to
perform name resolution. They will always use the network to perform DNS
queries. These functions do not use the same set of configuration files used by
[`dns.lookup()`][] (e.g. `/etc/hosts`). Use these functions to always perform
DNS queries, bypassing other name-resolution facilities.

```mjs
import dns from 'node:dns';
dns.resolve4('archive.org', (err, addresses) => {
if (err) throw err;
console.log(`addresses: ${JSON.stringify(addresses)}`);
addresses.forEach((a) => {
dns.reverse(a, (err, hostnames) => {
if (err) {
throw err;
}
console.log(`reverse for ${a}: ${JSON.stringify(hostnames)}`);
});
});
});
```
```cjs
const dns = require('node:dns');
dns.resolve4('archive.org', (err, addresses) => {
if (err) throw err;
console.log(`addresses: ${JSON.stringify(addresses)}`);
addresses.forEach((a) => {
dns.reverse(a, (err, hostnames) => {
if (err) {
throw err;
}
console.log(`reverse for ${a}: ${JSON.stringify(hostnames)}`);

## Class: `dns.Resolver`
<!-- YAML
added: v8.3.0
-->
An independent resolver for DNS requests.
Creating a new resolver uses the default server settings. Setting
the servers used for a resolver using
[`resolver.setServers()`][`dns.setServers()`] does not affect
other resolvers:
```mjs
import { Resolver } from 'node:dns';
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);
// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org', (err, addresses) => {
// ...
});
```
```cjs
const { Resolver } = require('node:dns');
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);
// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org', (err, addresses) => {
// ...
});
```
The following methods from the `node:dns` module are available:
* [`resolver.getServers()`][`dns.getServers()`]
* [`resolver.resolve()`][`dns.resolve()`]
* [`resolver.resolve4()`][`dns.resolve4()`]

2021-05-11, Version 14.17.0 'Fermium' (LTS) Notable Changes: Diagnostics channel (experimental module): `diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale. With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); MySQL.prototype.query = function query(queryString, values, callback) { // Broadcast query information whenever a query is made channel.publish({ query: queryString, host: this.hostname, }); this.doQuery(queryString, values, callback); }; ``` Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); channel.subscribe(({ query, host }) => { console.log(`mysql query to ${host}: ${query}`); }); ``` The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting. Contributed by Stephen Belanger (https://github.com/nodejs/node/pull/34895). UUID support in the crypto module: The new `crypto.randomUUID()` method now allows to generate random [RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings: ```js const { randomUUID } = require('crypto'); console.log(randomUUID()); // 'aa7c91a1-f8fc-4339-b9db-f93fc7233429' ``` Contributed by James M Snell (https://github.com/nodejs/node/pull/36729). Experimental support for `AbortController` and `AbortSignal`: Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`. Both constructors can be enabled globally using the `--experimental-abortcontroller` flag. Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible. `AbortSignal` support was added to the following methods: * `child_process.exec` * `child_process.execFile` * `child_process.fork` * `child_process.spawn` * `dgram.createSocket` * `events.on` * `events.once` * `fs.readFile` * `fs.watch` * `fs.writeFile` * `http.request` * `https.request` * `http2Session.request` * The promisified variants of `setImmediate` and `setTimeout` Other notable changes: * doc: * revoke deprecation of legacy url, change status to legacy (James M Snell) (https://github.com/nodejs/node/pull/37784) * add legacy status to stability index (James M Snell) (https://github.com/nodejs/node/pull/37784) * upgrade stability status of report API (Gireesh Punathil) (https://github.com/nodejs/node/pull/35654) * deps: * V8: Backport various patches for Apple Silicon support (BoHong Li) (https://github.com/nodejs/node/pull/38051) * update ICU to 68.1 (Michaël Zasso) (https://github.com/nodejs/node/pull/36187) * upgrade to libuv 1.41.0 (Colin Ihrig) (https://github.com/nodejs/node/pull/37360) * http: * add http.ClientRequest.getRawHeaderNames() (simov) (https://github.com/nodejs/node/pull/37660) * report request start and end with diagnostics\_channel (Stephen Belanger) (https://github.com/nodejs/node/pull/34895) * util: * add getSystemErrorMap() impl (eladkeyshawn) (https://github.com/nodejs/node/pull/38101) PR-URL: https://github.com/nodejs/node/pull/38507

* `ipv4` {string} A string representation of an IPv4 address.
**Default:** `'0.0.0.0'`
* `ipv6` {string} A string representation of an IPv6 address.
**Default:** `'::0'`
The resolver instance will send its requests from the specified IP address.
This allows programs to specify outbound interfaces when used on multi-homed
systems.
If a v4 or v6 address is not specified, it is set to the default and the
operating system will choose a local address automatically.
The resolver will use the v4 local address when making requests to IPv4 DNS
servers, and the v6 local address when making requests to IPv6 DNS servers.
The `rrtype` of resolution requests has no impact on the local address used.
## `dns.getServers()`
<!-- YAML
added: v0.11.3
-->
* Returns: {string\[]}
Returns an array of IP address strings, formatted according to [RFC 5952][],
that are currently configured for DNS resolution. A string will include a port
section if a custom port is used.

The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

While OpenSSL 3.0 APIs should be mostly compatible with those provided by OpenSSL 1.1.1, we do anticipate some ecosystem impact due to tightened restrictions on the allowed algorithms and key sizes. If you hit an `ERR_OSSL_EVP_UNSUPPORTED` error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A command-line option, `--openssl-legacy-provider`, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions. For details about all the features in OpenSSL 3.0 please see https://www.openssl.org/blog/blog/2021/09/07/OpenSSL3.Final.

-->
* `hostname` {string}
* `options` {integer | Object}
* `family` {integer|string} The record family. Must be `4`, `6`, or `0`. For
backward compatibility reasons,`'IPv4'` and `'IPv6'` are interpreted as `4`
and `6` respectively. The value `0` indicates that either an IPv4 or IPv6
address is returned. If the value `0` is used with `{ all: true }` (see
below), either one of or both IPv4 and IPv6 addresses are returned,
depending on the system's DNS resolver. **Default:** `0`.
* `hints` {number} One or more [supported `getaddrinfo` flags][]. Multiple
flags may be passed by bitwise `OR`ing their values.
* `all` {boolean} When `true`, the callback returns all resolved addresses in
an array. Otherwise, returns a single address. **Default:** `false`.
* `order` {string} When `verbatim`, the resolved addresses are return
unsorted. When `ipv4first`, the resolved addresses are sorted by placing
IPv4 addresses before IPv6 addresses. When `ipv6first`, the resolved
addresses are sorted by placing IPv6 addresses before IPv4 addresses.
**Default:** `verbatim` (addresses are not reordered).
Default value is configurable using [`dns.setDefaultResultOrder()`][] or
[`--dns-result-order`][].
* `verbatim` {boolean} When `true`, the callback receives IPv4 and IPv6
addresses in the order the DNS resolver returned them. When `false`,
IPv4 addresses are placed before IPv6 addresses.
This option will be deprecated in favor of `order`. When both are specified,
`order` has higher precedence. New code should only use `order`.
**Default:** `true` (addresses are not reordered). Default value is
configurable using [`dns.setDefaultResultOrder()`][] or
[`--dns-result-order`][].
* `callback` {Function}
* `err` {Error}
* `address` {string} A string representation of an IPv4 or IPv6 address.
* `family` {integer} `4` or `6`, denoting the family of `address`, or `0` if
the address is not an IPv4 or IPv6 address. `0` is a likely indicator of a
bug in the name resolution service used by the operating system.
2010-10-28 23:18:16 +11:00
Resolves a host name (e.g. `'nodejs.org'`) into the first found A (IPv4) or
AAAA (IPv6) record. All `option` properties are optional. If `options` is an
integer, then it must be `4` or `6` if `options` is not provided, then
either IPv4 or IPv6 addresses, or both, are returned if found.
With the `all` option set to `true`, the arguments for `callback` change to
`(err, addresses)`, with `addresses` being an array of objects with the
properties `address` and `family`.
2010-10-28 23:18:16 +11:00
On error, `err` is an [`Error`][] object, where `err.code` is the error code.
Keep in mind that `err.code` will be set to `'ENOTFOUND'` not only when
the host name does not exist but also when the lookup fails in other ways
2012-04-18 15:56:14 +02:00
such as no available file descriptors.
`dns.lookup()` does not necessarily have anything to do with the DNS protocol.
The implementation uses an operating system facility that can associate names
with addresses and vice versa. This implementation can have subtle but
important consequences on the behavior of any Node.js program. Please take some
time to consult the [Implementation considerations section][] before using
`dns.lookup()`.
Example usage:
```mjs
import dns from 'node:dns';
const options = {
family: 6,
hints: dns.ADDRCONFIG | dns.V4MAPPED,
};
dns.lookup('example.org', options, (err, address, family) =>
console.log('address: %j family: IPv%s', address, family));
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6
// When options.all is true, the result will be an Array.
options.all = true;
dns.lookup('example.org', options, (err, addresses) =>
console.log('addresses: %j', addresses));
// addresses: [{"address":"2606:2800:21f:cb07:6820:80da:af6b:8b2c","family":6}]
```
```cjs
const dns = require('node:dns');
const options = {
family: 6,
hints: dns.ADDRCONFIG | dns.V4MAPPED,
};
dns.lookup('example.org', options, (err, address, family) =>
console.log('address: %j family: IPv%s', address, family));
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6
// When options.all is true, the result will be an Array.
options.all = true;
dns.lookup('example.org', options, (err, addresses) =>
console.log('addresses: %j', addresses));
// addresses: [{"address":"2606:2800:21f:cb07:6820:80da:af6b:8b2c","family":6}]
```
If this method is invoked as its [`util.promisify()`][]ed version, and `all`
is not set to `true`, it returns a `Promise` for an `Object` with `address` and
`family` properties.

- v13.13.0
- v12.17.0
pr-url: https://github.com/nodejs/node/pull/32183
description: Added support for the `dns.ALL` flag.
-->
The following flags can be passed as hints to [`dns.lookup()`][].
* `dns.ADDRCONFIG`: Limits returned address types to the types of non-loopback
addresses configured on the system. For example, IPv4 addresses are only
returned if the current system has at least one IPv4 address configured.
* `dns.V4MAPPED`: If the IPv6 family was specified, but no IPv6 addresses were
found, then return IPv4 mapped IPv6 addresses. It is not supported
on some operating systems (e.g. FreeBSD 10.1).
* `dns.ALL`: If `dns.V4MAPPED` is specified, return resolved IPv6 addresses as
well as IPv4 mapped IPv6 addresses.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`. Contributed James Snell in https://github.com/nodejs/node/pull/39062, and Antoine du Hamel in https://github.com/nodejs/node/pull/42225.

* `port` {number}
* `callback` {Function}
* `err` {Error}
* `hostname` {string} e.g. `example.com`
* `service` {string} e.g. `http`
Resolves the given `address` and `port` into a host name and service using
the operating system's underlying `getnameinfo` implementation.
If `address` is not a valid IP address, a `TypeError` will be thrown.
The `port` will be coerced to a number. If it is not a legal port, a `TypeError`
will be thrown.
On an error, `err` is an [`Error`][] object, where `err.code` is the error code.
```mjs
import dns from 'node:dns';
dns.lookupService('127.0.0.1', 22, (err, hostname, service) => {
console.log(hostname, service);
// Prints: localhost ssh
});
```
```cjs
const dns = require('node:dns');
dns.lookupService('127.0.0.1', 22, (err, hostname, service) => {
console.log(hostname, service);
// Prints: localhost ssh
});
```
If this method is invoked as its [`util.promisify()`][]ed version, it returns a
`Promise` for an `Object` with `hostname` and `service` properties.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file.

-->
* `hostname` {string} Host name to resolve.
* `rrtype` {string} Resource record type. **Default:** `'A'`.
* `callback` {Function}
* `err` {Error}
* `records` {string\[] | Object\[] | Object}
Uses the DNS protocol to resolve a host name (e.g. `'nodejs.org'`) into an array
of the resource records. The `callback` function has arguments
`(err, records)`. When successful, `records` will be an array of resource
records. The type and structure of individual results varies based on `rrtype`:
| `rrtype` | `records` contains | Result type | Shorthand method |
| --------- | ------------------------------ | ----------- | ------------------------ |
| `'A'` | IPv4 addresses (default) | {string} | [`dns.resolve4()`][] |
| `'AAAA'` | IPv6 addresses | {string} | [`dns.resolve6()`][] |
| `'ANY'` | any records | {Object} | [`dns.resolveAny()`][] |
| `'CAA'` | CA authorization records | {Object} | [`dns.resolveCaa()`][] |
| `'CNAME'` | canonical name records | {string} | [`dns.resolveCname()`][] |
| `'MX'` | mail exchange records | {Object} | [`dns.resolveMx()`][] |
| `'NAPTR'` | name authority pointer records | {Object} | [`dns.resolveNaptr()`][] |
| `'NS'` | name server records | {string} | [`dns.resolveNs()`][] |
| `'PTR'` | pointer records | {string} | [`dns.resolvePtr()`][] |
| `'SOA'` | start of authority records | {Object} | [`dns.resolveSoa()`][] |

| `'TLSA'` | certificate associations | {Object} | [`dns.resolveTlsa()`][] |
| `'TXT'` | text records | {string\[]} | [`dns.resolveTxt()`][] |
On error, `err` is an [`Error`][] object, where `err.code` is one of the
[DNS error codes][].

Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file.

V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`. Contributed James Snell in https://github.com/nodejs/node/pull/39062, and Antoine du Hamel in https://github.com/nodejs/node/pull/42225.

description: Passing an invalid callback to the `callback` argument
now throws `ERR_INVALID_ARG_TYPE` instead of
`ERR_INVALID_CALLBACK`.
-->
* `hostname` {string}
* `callback` {Function}
* `err` {Error}
* `ret` {Object\[]}
Uses the DNS protocol to resolve all records (also known as `ANY` or `*` query).
The `ret` argument passed to the `callback` function will be an array containing
various types of records. Each object has a property `type` that indicates the
type of the current record. And depending on the `type`, additional properties
will be present on the object:
| Type | Properties |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| `'A'` | `address`/`ttl` |
| `'AAAA'` | `address`/`ttl` |
| `'CNAME'` | `value` |
| `'MX'` | Refer to [`dns.resolveMx()`][] |
| `'NAPTR'` | Refer to [`dns.resolveNaptr()`][] |
| `'NS'` | `value` |
| `'PTR'` | `value` |
| `'SOA'` | Refer to [`dns.resolveSoa()`][] |
| `'SRV'` | Refer to [`dns.resolveSrv()`][] |
| `'TLSA'` | Refer to [`dns.resolveTlsa()`][] |
| `'TXT'` | This type of record contains an array property called `entries` which refers to [`dns.resolveTxt()`][], e.g. `{ entries: ['...'], type: 'TXT' }` |
Here is an example of the `ret` object passed to the callback:
<!-- eslint-disable @stylistic/js/semi -->
```js
[ { type: 'A', address: '127.0.0.1', ttl: 299 },
{ type: 'CNAME', value: 'example.com' },
{ type: 'MX', exchange: 'alt4.aspmx.l.example.com', priority: 50 },
{ type: 'NS', value: 'ns1.example.com' },
{ type: 'TXT', entries: [ 'v=spf1 include:_spf.example.com ~all' ] },
{ type: 'SOA',
nsname: 'ns1.example.com',
hostmaster: 'admin.example.com',
serial: 156696742,
refresh: 900,
retry: 900,
expire: 1800,
minttl: 60 } ]
```
DNS server operators may choose not to respond to `ANY`
queries. It may be better to call individual methods like [`dns.resolve4()`][],
[`dns.resolveMx()`][], and so on. For more details, see [RFC 8482][].

description: Passing an invalid callback to the `callback` argument
now throws `ERR_INVALID_ARG_TYPE` instead of
`ERR_INVALID_CALLBACK`.
-->
* `hostname` {string}
* `callback` {Function}
* `err` {Error}
* `addresses` {string\[]}
Uses the DNS protocol to resolve `CNAME` records for the `hostname`. The
`addresses` argument passed to the `callback` function
will contain an array of canonical name records available for the `hostname`
(e.g. `['bar.example.com']`).

2021-05-11, Version 14.17.0 'Fermium' (LTS) Notable Changes: Diagnostics channel (experimental module): `diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale. With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); MySQL.prototype.query = function query(queryString, values, callback) { // Broadcast query information whenever a query is made channel.publish({ query: queryString, host: this.hostname, }); this.doQuery(queryString, values, callback); }; ``` Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); channel.subscribe(({ query, host }) => { console.log(`mysql query to ${host}: ${query}`); }); ``` The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting. Contributed by Stephen Belanger (https://github.com/nodejs/node/pull/34895). UUID support in the crypto module: The new `crypto.randomUUID()` method now allows to generate random [RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings: ```js const { randomUUID } = require('crypto'); console.log(randomUUID()); // 'aa7c91a1-f8fc-4339-b9db-f93fc7233429' ``` Contributed by James M Snell (https://github.com/nodejs/node/pull/36729). Experimental support for `AbortController` and `AbortSignal`: Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`. Both constructors can be enabled globally using the `--experimental-abortcontroller` flag. Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible. `AbortSignal` support was added to the following methods: * `child_process.exec` * `child_process.execFile` * `child_process.fork` * `child_process.spawn` * `dgram.createSocket` * `events.on` * `events.once` * `fs.readFile` * `fs.watch` * `fs.writeFile` * `http.request` * `https.request` * `http2Session.request` * The promisified variants of `setImmediate` and `setTimeout` Other notable changes: * doc: * revoke deprecation of legacy url, change status to legacy (James M Snell) (https://github.com/nodejs/node/pull/37784) * add legacy status to stability index (James M Snell) (https://github.com/nodejs/node/pull/37784) * upgrade stability status of report API (Gireesh Punathil) (https://github.com/nodejs/node/pull/35654) * deps: * V8: Backport various patches for Apple Silicon support (BoHong Li) (https://github.com/nodejs/node/pull/38051) * update ICU to 68.1 (Michaël Zasso) (https://github.com/nodejs/node/pull/36187) * upgrade to libuv 1.41.0 (Colin Ihrig) (https://github.com/nodejs/node/pull/37360) * http: * add http.ClientRequest.getRawHeaderNames() (simov) (https://github.com/nodejs/node/pull/37660) * report request start and end with diagnostics\_channel (Stephen Belanger) (https://github.com/nodejs/node/pull/34895) * util: * add getSystemErrorMap() impl (eladkeyshawn) (https://github.com/nodejs/node/pull/38101) PR-URL: https://github.com/nodejs/node/pull/38507

changes:
2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

Uses the DNS protocol to resolve mail exchange records (`MX` records) for the

contain an array of objects containing both a `priority` and `exchange`
property (e.g. `[{priority: 10, exchange: 'mx.example.com'}, ...]`).

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

2022-04-19, Version 18.0.0 (Current) Notable Changes: Deprecations and Removals: - (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`, `fs.writeFileSync` (Livia Medeiros) (https://github.com/nodejs/node/pull/42607) - (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup` options type coercion (Antoine du Hamel) (https://github.com/nodejs/node/pull/41431) - (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) (https://github.com/nodejs/node/pull/41896) - (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) (https://github.com/nodejs/node/pull/40773) - (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) (https://github.com/nodejs/node/pull/41479) fetch (experimental): An experimental fetch API is available on the global scope by default. The implementation is based upon https://undici.nodejs.org/#/, an HTTP/1.1 client written for Node.js by contributors to the project. Through this addition, the following globals are made available: `fetch` , `FormData`, `Headers`, `Request`, `Response`. Disable this API with the `--no-experimental-fetch` command-line flag. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/41811. HTTP Timeouts: `server.headersTimeout`, which limits the amount of time the parser will wait to receive the complete HTTP headers, is now set to `60000` (60 seconds) by default. `server.requestTimeout`, which sets the timeout value in milliseconds for receiving the entire request from the client, is now set to `300000` (5 minutes) by default. If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection. Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front. Contributed by Paolo Insogna in https://github.com/nodejs/node/pull/41263. Test Runner module (experimental): The `node:test` module facilitates the creation of JavaScript tests that report results in TAP format. This module is only available under the `node:` scheme. Contributed by Colin Ihrig in https://github.com/nodejs/node/pull/42325. Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

Toolchain and Compiler Upgrades: - Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04. - Prebuilt binaries for macOS now require macOS 10.15 or later. - For AIX the minimum supported architecture has been raised from Power 7 to Power 8. Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update. Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date. Full details about the supported toolchains and compilers are documented in the Node.js `BUILDING.md` file. Contributed by Richard Lau in https://github.com/nodejs/node/pull/42292, https://github.com/nodejs/node/pull/42604 and https://github.com/nodejs/node/pull/42659 , and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and https://github.com/nodejs/node/pull/42666. V8 10.1: The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included: - The `findLast` and `findLastIndex` array methods. - Improvements to the `Intl.Locale` API. - The `Intl.supportedValuesOf` function. - Improved performance of class fields and private class methods (the initialization of them is now as fast as ordinary property stores). The data format returned by the serialization API (`v8.serialize(value)`) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible. Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657. Web Streams API (experimental): Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available: - `ReadableStream`, `ReadableStreamDefaultReader`, `ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`, `ReadableByteStreamController`, `ReadableStreamDefaultController`, `TransformStream`, `TransformStreamDefaultController`, `WritableStream`, `WritableStreamDefaultWriter`, `WritableStreamDefaultController`, `ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`, `TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

Uses the DNS protocol to resolve text queries (`TXT` records) for the
`hostname`. The `records` argument passed to the `callback` function is a
two-dimensional array of the text records available for `hostname` (e.g.
`[ ['v=spf1 ip4:0.0.0.0 ', '~all' ] ]`). Each sub-array contains TXT chunks of
one record. Depending on the use case, these could be either joined together or
treated separately.

2023-07-18, Version 18.17.0 'Hydrogen' (LTS) Notable changes: Ada 2.0 Node.js v18.17.0 comes with the latest version of the URL parser, Ada. This update brings significant performance improvements to URL parsing, including enhancements to the url.domainToASCII and url.domainToUnicode functions in node:url. Ada 2.0 has been integrated into the Node.js codebase, ensuring that all parts of the application can benefit from the improved performance. Additionally, Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4, while also eliminating the need for the ICU requirement for URL hostname parsing.

description: The `ipv6first` value is supported now.
-->
Get the default value for `order` in [`dns.lookup()`][] and
[`dnsPromises.lookup()`][]. The value could be:
* `ipv4first`: for `order` defaulting to `ipv4first`.
* `ipv6first`: for `order` defaulting to `ipv6first`.
* `verbatim`: for `order` defaulting to `verbatim`.
## `dns.setServers(servers)`
<!-- YAML
added: v0.11.3
-->
* `servers` {string\[]} array of [RFC 5952][] formatted addresses
Sets the IP address and port of servers to be used when performing DNS
resolution. The `servers` argument is an array of [RFC 5952][] formatted
addresses. If the port is the IANA default DNS port (53) it can be omitted.
```js
dns.setServers([
'8.8.8.8',
'[2001:4860:4860::8888]',
'8.8.8.8:1053',
'[2001:4860:4860::8888]:1053',
]);
```
An error will be thrown if an invalid address is provided.
The `dns.setServers()` method must not be called while a DNS query is in
progress.
The [`dns.setServers()`][] method affects only [`dns.resolve()`][],
`dns.resolve*()` and [`dns.reverse()`][] (and specifically _not_
[`dns.lookup()`][]).
This method works much like
[resolve.conf](https://man7.org/linux/man-pages/man5/resolv.conf.5.html).
That is, if attempting to resolve with the first server provided results in a
`NOTFOUND` error, the `resolve()` method will _not_ attempt to resolve with
subsequent servers provided. Fallback DNS servers will only be used if the
earlier ones time out or result in some other error.

The `dns.promises` API provides an alternative set of asynchronous DNS methods
that return `Promise` objects rather than using callbacks. The API is accessible
via `require('node:dns').promises` or `require('node:dns/promises')`.

An independent resolver for DNS requests.
Creating a new resolver uses the default server settings. Setting
the servers used for a resolver using
[`resolver.setServers()`][`dnsPromises.setServers()`] does not affect
other resolvers:
```mjs
import { Resolver } from 'node:dns/promises';
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);
// This request will use the server at 4.4.4.4, independent of global settings.
const addresses = await resolver.resolve4('example.org');
```
```cjs
const { Resolver } = require('node:dns').promises;
const resolver = new Resolver();
resolver.setServers(['4.4.4.4']);
// This request will use the server at 4.4.4.4, independent of global settings.
resolver.resolve4('example.org').then((addresses) => {
// ...
});
// Alternatively, the same code can be written using async-await style.
(async function() {
const addresses = await resolver.resolve4('example.org');
})();
```
The following methods from the `dnsPromises` API are available:
* [`resolver.getServers()`][`dnsPromises.getServers()`]
* [`resolver.resolve()`][`dnsPromises.resolve()`]
* [`resolver.resolve4()`][`dnsPromises.resolve4()`]
* [`resolver.resolve6()`][`dnsPromises.resolve6()`]

2021-05-11, Version 14.17.0 'Fermium' (LTS) Notable Changes: Diagnostics channel (experimental module): `diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale. With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); MySQL.prototype.query = function query(queryString, values, callback) { // Broadcast query information whenever a query is made channel.publish({ query: queryString, host: this.hostname, }); this.doQuery(queryString, values, callback); }; ``` Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); channel.subscribe(({ query, host }) => { console.log(`mysql query to ${host}: ${query}`); }); ``` The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting. Contributed by Stephen Belanger (https://github.com/nodejs/node/pull/34895). UUID support in the crypto module: The new `crypto.randomUUID()` method now allows to generate random [RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings: ```js const { randomUUID } = require('crypto'); console.log(randomUUID()); // 'aa7c91a1-f8fc-4339-b9db-f93fc7233429' ``` Contributed by James M Snell (https://github.com/nodejs/node/pull/36729). Experimental support for `AbortController` and `AbortSignal`: Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`. Both constructors can be enabled globally using the `--experimental-abortcontroller` flag. Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible. `AbortSignal` support was added to the following methods: * `child_process.exec` * `child_process.execFile` * `child_process.fork` * `child_process.spawn` * `dgram.createSocket` * `events.on` * `events.once` * `fs.readFile` * `fs.watch` * `fs.writeFile` * `http.request` * `https.request` * `http2Session.request` * The promisified variants of `setImmediate` and `setTimeout` Other notable changes: * doc: * revoke deprecation of legacy url, change status to legacy (James M Snell) (https://github.com/nodejs/node/pull/37784) * add legacy status to stability index (James M Snell) (https://github.com/nodejs/node/pull/37784) * upgrade stability status of report API (Gireesh Punathil) (https://github.com/nodejs/node/pull/35654) * deps: * V8: Backport various patches for Apple Silicon support (BoHong Li) (https://github.com/nodejs/node/pull/38051) * update ICU to 68.1 (Michaël Zasso) (https://github.com/nodejs/node/pull/36187) * upgrade to libuv 1.41.0 (Colin Ihrig) (https://github.com/nodejs/node/pull/37360) * http: * add http.ClientRequest.getRawHeaderNames() (simov) (https://github.com/nodejs/node/pull/37660) * report request start and end with diagnostics\_channel (Stephen Belanger) (https://github.com/nodejs/node/pull/34895) * util: * add getSystemErrorMap() impl (eladkeyshawn) (https://github.com/nodejs/node/pull/38101) PR-URL: https://github.com/nodejs/node/pull/38507

-->
* `hostname` {string}
* `options` {integer | Object}
* `family` {integer} The record family. Must be `4`, `6`, or `0`. The value
`0` indicates that either an IPv4 or IPv6 address is returned. If the
value `0` is used with `{ all: true }` (see below), either one of or both
IPv4 and IPv6 addresses are returned, depending on the system's DNS
resolver. **Default:** `0`.

flags may be passed by bitwise `OR`ing their values.
* `all` {boolean} When `true`, the `Promise` is resolved with all addresses in
an array. Otherwise, returns a single address. **Default:** `false`.
* `order` {string} When `verbatim`, the `Promise` is resolved with IPv4 and
IPv6 addresses in the order the DNS resolver returned them. When `ipv4first`,
IPv4 addresses are placed before IPv6 addresses. When `ipv6first`,
IPv6 addresses are placed before IPv4 addresses.
**Default:** `verbatim` (addresses are not reordered).
Default value is configurable using [`dns.setDefaultResultOrder()`][] or
[`--dns-result-order`][]. New code should use `{ order: 'verbatim' }`.
* `verbatim` {boolean} When `true`, the `Promise` is resolved with IPv4 and
IPv6 addresses in the order the DNS resolver returned them. When `false`,
IPv4 addresses are placed before IPv6 addresses.
This option will be deprecated in favor of `order`. When both are specified,
`order` has higher precedence. New code should only use `order`.
**Default:** currently `false` (addresses are reordered) but this is
expected to change in the not too distant future. Default value is
configurable using [`dns.setDefaultResultOrder()`][] or
[`--dns-result-order`][].
Resolves a host name (e.g. `'nodejs.org'`) into the first found A (IPv4) or
AAAA (IPv6) record. All `option` properties are optional. If `options` is an
integer, then it must be `4` or `6` if `options` is not provided, then
either IPv4 or IPv6 addresses, or both, are returned if found.
With the `all` option set to `true`, the `Promise` is resolved with `addresses`
being an array of objects with the properties `address` and `family`.
On error, the `Promise` is rejected with an [`Error`][] object, where `err.code`
is the error code.
Keep in mind that `err.code` will be set to `'ENOTFOUND'` not only when
the host name does not exist but also when the lookup fails in other ways
such as no available file descriptors.
[`dnsPromises.lookup()`][] does not necessarily have anything to do with the DNS
protocol. The implementation uses an operating system facility that can
associate names with addresses and vice versa. This implementation can have
subtle but important consequences on the behavior of any Node.js program. Please
take some time to consult the [Implementation considerations section][] before
using `dnsPromises.lookup()`.
Example usage:
```mjs
import dns from 'node:dns';
const dnsPromises = dns.promises;
const options = {
family: 6,
hints: dns.ADDRCONFIG | dns.V4MAPPED,
};
await dnsPromises.lookup('example.org', options).then((result) => {
console.log('address: %j family: IPv%s', result.address, result.family);
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6
});
// When options.all is true, the result will be an Array.
options.all = true;
await dnsPromises.lookup('example.org', options).then((result) => {
console.log('addresses: %j', result);
// addresses: [{"address":"2606:2800:21f:cb07:6820:80da:af6b:8b2c","family":6}]
});
```
```cjs
const dns = require('node:dns');
const dnsPromises = dns.promises;
const options = {
family: 6,
hints: dns.ADDRCONFIG | dns.V4MAPPED,
};
dnsPromises.lookup('example.org', options).then((result) => {
console.log('address: %j family: IPv%s', result.address, result.family);
// address: "2606:2800:21f:cb07:6820:80da:af6b:8b2c" family: IPv6

### `dnsPromises.resolveCaa(hostname)`
<!-- YAML
2021-05-11, Version 14.17.0 'Fermium' (LTS) Notable Changes: Diagnostics channel (experimental module): `diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0 to enable testing it at a larger scale. With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); MySQL.prototype.query = function query(queryString, values, callback) { // Broadcast query information whenever a query is made channel.publish({ query: queryString, host: this.hostname, }); this.doQuery(queryString, values, callback); }; ``` Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel. ```js const dc = require('diagnostics_channel'); const channel = dc.channel('mysql.query'); channel.subscribe(({ query, host }) => { console.log(`mysql query to ${host}: ${query}`); }); ``` The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting. Contributed by Stephen Belanger (https://github.com/nodejs/node/pull/34895). UUID support in the crypto module: The new `crypto.randomUUID()` method now allows to generate random [RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings: ```js const { randomUUID } = require('crypto'); console.log(randomUUID()); // 'aa7c91a1-f8fc-4339-b9db-f93fc7233429' ``` Contributed by James M Snell (https://github.com/nodejs/node/pull/36729). Experimental support for `AbortController` and `AbortSignal`: Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`. Both constructors can be enabled globally using the `--experimental-abortcontroller` flag. Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation. It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives should be compatible. `AbortSignal` support was added to the following methods: * `child_process.exec` * `child_process.execFile` * `child_process.fork` * `child_process.spawn` * `dgram.createSocket` * `events.on` * `events.once` * `fs.readFile` * `fs.watch` * `fs.writeFile` * `http.request` * `https.request` * `http2Session.request` * The promisified variants of `setImmediate` and `setTimeout` Other notable changes: * doc: * revoke deprecation of legacy url, change status to legacy (James M Snell) (https://github.com/nodejs/node/pull/37784) * add legacy status to stability index (James M Snell) (https://github.com/nodejs/node/pull/37784) * upgrade stability status of report API (Gireesh Punathil) (https://github.com/nodejs/node/pull/35654) * deps: * V8: Backport various patches for Apple Silicon support (BoHong Li) (https://github.com/nodejs/node/pull/38051) * update ICU to 68.1 (Michaël Zasso) (https://github.com/nodejs/node/pull/36187) * upgrade to libuv 1.41.0 (Colin Ihrig) (https://github.com/nodejs/node/pull/37360) * http: * add http.ClientRequest.getRawHeaderNames() (simov) (https://github.com/nodejs/node/pull/37660) * report request start and end with diagnostics\_channel (Stephen Belanger) (https://github.com/nodejs/node/pull/34895) * util: * add getSystemErrorMap() impl (eladkeyshawn) (https://github.com/nodejs/node/pull/38101) PR-URL: https://github.com/nodejs/node/pull/38507

-->
* `order` {string} must be `'ipv4first'`, `'ipv6first'` or `'verbatim'`.
Set the default value of `order` in [`dns.lookup()`][] and
[`dnsPromises.lookup()`][]. The value could be:
* `ipv4first`: sets default `order` to `ipv4first`.
* `ipv6first`: sets default `order` to `ipv6first`.
* `verbatim`: sets default `order` to `verbatim`.
The default is `verbatim` and [`dnsPromises.setDefaultResultOrder()`][] have
higher priority than [`--dns-result-order`][]. When using [worker threads][],
[`dnsPromises.setDefaultResultOrder()`][] from the main thread won't affect the
default dns orders in workers.

2023-07-18, Version 18.17.0 'Hydrogen' (LTS) Notable changes: Ada 2.0 Node.js v18.17.0 comes with the latest version of the URL parser, Ada. This update brings significant performance improvements to URL parsing, including enhancements to the url.domainToASCII and url.domainToUnicode functions in node:url. Ada 2.0 has been integrated into the Node.js codebase, ensuring that all parts of the application can benefit from the improved performance. Additionally, Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4, while also eliminating the need for the ICU requirement for URL hostname parsing.

2018-07-04, Version 10.6.0 (Current) Notable changes: * dns: * An experimental promisified version of the dns module is now available. Give it a try with `require('dns').promises`. [#21264](https://github.com/nodejs/node/pull/21264) * fs: * `fs.lchown` has been undeprecated now that libuv supports it. [#21498](https://github.com/nodejs/node/pull/21498) * lib: * `Atomics.wake` is being renamed to `Atomics.notify` in the ECMAScript specification ([reference](https://github.com/tc39/ecma262/pull/1220)). Since Node.js now has experimental support for worker threads, we are being proactive and added a `notify` alias, while emitting a warning if `wake` is used. [#21413](https://github.com/nodejs/node/pull/21413) [#21518](https://github.com/nodejs/node/pull/21518) * n-api: * Add API for asynchronous functions. [#17887](https://github.com/nodejs/node/pull/17887) * util: * `util.inspect` is now able to return a result instead of throwing when the maximum call stack size is exceeded during inspection. [#20725](https://github.com/nodejs/node/pull/20725) * vm: * Add `script.createCachedData()`. This API replaces the `produceCachedData` option of the `Script` constructor that is now deprecated. [#20300](https://github.com/nodejs/node/pull/20300) * worker: * Support for relative paths has been added to the `Worker` constructor. Paths are interpreted relative to the current working directory.

* `servers` {string\[]} array of [RFC 5952][] formatted addresses
Sets the IP address and port of servers to be used when performing DNS
resolution. The `servers` argument is an array of [RFC 5952][] formatted
addresses. If the port is the IANA default DNS port (53) it can be omitted.
```js
dnsPromises.setServers([
'8.8.8.8',
'[2001:4860:4860::8888]',
'8.8.8.8:1053',
'[2001:4860:4860::8888]:1053',
]);
```
An error will be thrown if an invalid address is provided.
The `dnsPromises.setServers()` method must not be called while a DNS query is in
progress.
This method works much like
[resolve.conf](https://man7.org/linux/man-pages/man5/resolv.conf.5.html).
That is, if attempting to resolve with the first server provided results in a
`NOTFOUND` error, the `resolve()` method will _not_ attempt to resolve with
subsequent servers provided. Fallback DNS servers will only be used if the
earlier ones time out or result in some other error.
2012-04-18 15:56:14 +02:00
## Error codes
Each DNS query can return one of the following error codes:
* `dns.NODATA`: DNS server returned an answer with no data.
* `dns.FORMERR`: DNS server claims query was misformatted.
* `dns.SERVFAIL`: DNS server returned general failure.
* `dns.NOTFOUND`: Domain name not found.
* `dns.NOTIMP`: DNS server does not implement the requested operation.
* `dns.REFUSED`: DNS server refused query.
* `dns.BADQUERY`: Misformatted DNS query.
* `dns.BADNAME`: Misformatted host name.
* `dns.BADFAMILY`: Unsupported address family.
* `dns.BADRESP`: Misformatted DNS reply.
* `dns.CONNREFUSED`: Could not contact DNS servers.
* `dns.TIMEOUT`: Timeout while contacting DNS servers.
* `dns.EOF`: End of file.
* `dns.FILE`: Error reading file.
* `dns.NOMEM`: Out of memory.
* `dns.DESTRUCTION`: Channel is being destroyed.
* `dns.BADSTR`: Misformatted string.
* `dns.BADFLAGS`: Illegal flags specified.
* `dns.NONAME`: Given host name is not numeric.
* `dns.BADHINTS`: Illegal hints flags specified.
* `dns.NOTINITIALIZED`: c-ares library initialization not yet performed.
* `dns.LOADIPHLPAPI`: Error loading `iphlpapi.dll`.
* `dns.ADDRGETNETWORKPARAMS`: Could not find `GetNetworkParams` function.
* `dns.CANCELLED`: DNS query cancelled.
The `dnsPromises` API also exports the above error codes, e.g., `dnsPromises.NODATA`.
## Implementation considerations
Although [`dns.lookup()`][] and the various `dns.resolve*()/dns.reverse()`
functions have the same goal of associating a network name with a network
address (or vice versa), their behavior is quite different. These differences
can have subtle but significant consequences on the behavior of Node.js
programs.
### `dns.lookup()`
Under the hood, [`dns.lookup()`][] uses the same operating system facilities
as most other programs. For instance, [`dns.lookup()`][] will almost always
resolve a given name the same way as the `ping` command. On most POSIX-like
operating systems, the behavior of the [`dns.lookup()`][] function can be
modified by changing settings in nsswitch.conf(5) and/or resolv.conf(5),
but changing these files will change the behavior of all other
programs running on the same operating system.
Though the call to `dns.lookup()` will be asynchronous from JavaScript's
perspective, it is implemented as a synchronous call to getaddrinfo(3) that runs
on libuv's threadpool. This can have surprising negative performance
implications for some applications, see the [`UV_THREADPOOL_SIZE`][]
documentation for more information.
Various networking APIs will call `dns.lookup()` internally to resolve
host names. If that is an issue, consider resolving the host name to an address
using `dns.resolve()` and using the address instead of a host name. Also, some
networking APIs (such as [`socket.connect()`][] and [`dgram.createSocket()`][])
allow the default resolver, `dns.lookup()`, to be replaced.
### `dns.resolve()`, `dns.resolve*()`, and `dns.reverse()`
These functions are implemented quite differently than [`dns.lookup()`][]. They
do not use getaddrinfo(3) and they _always_ perform a DNS query on the
network. This network communication is always done asynchronously and does not
use libuv's threadpool.
As a result, these functions cannot have the same negative impact on other
processing that happens on libuv's threadpool that [`dns.lookup()`][] can have.
They do not use the same set of configuration files that [`dns.lookup()`][]
uses. For instance, they do not use the configuration from `/etc/hosts`.
