/**
* The `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)](https://en.wikipedia.org/wiki/Domain_Name_System), it does not always use the
* DNS protocol for lookups. {@link 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 {@link lookup}.
*
* ```js
* const dns = require('dns');
*
* dns.lookup('example.org', (err, address, family) => {
* console.log('address: %j family: IPv%s', address, family);
* });
* // address: "93.184.216.34" family: IPv4
* ```
*
* All other functions in the `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 {@link lookup} (e.g. `/etc/hosts`). Use these functions to always perform
* DNS queries, bypassing other name-resolution facilities.
*
* ```js
* const dns = require('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)}`);
* });
* });
* });
* ```
*
* See the `Implementation considerations section` for more information.
* @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/dns.js)

/**
* 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 IPv4
* and IPv6 addresses are both 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`.
*
* 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
* 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:
*
* ```js
* const dns = require('dns');
* const options = {
* family: 6,
* hints: dns.ADDRCONFIG | dns.V4MAPPED,
* };
* dns.lookup('example.com', options, (err, address, family) =>
* console.log('address: %j family: IPv%s', address, family));
* // address: "2606:2800:220:1:248:1893:25c8:1946" family: IPv6
*
* // When options.all is true, the result will be an Array.
* options.all = true;
* dns.lookup('example.com', options, (err, addresses) =>
* console.log('addresses: %j', addresses));
* // addresses: [{"address":"2606:2800:220:1:248:1893:25c8:1946","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.
* @since v0.1.90
