is-localhost-ip

Comprehensive and robust library to checks whether given host name or IPv4/IPv6 address belongs to the local machine

Main difference from other libraries here is comprehensiveness: we start from strict RegExp checks (for IP address first, and then for correctness to be a host name), then fallback to DNS resolver (so it works with something like john.dev remapped locally in hosts or with local resolver).

All this in just ~100 lines of code without external dependencies.

Installation

1npm i is-localhost-ip
2# or
3yarn add is-localhost-ip

Example

1const isLocalhost = require('is-localhost-ip');
2
3(async () => {
4  await isLocalhost('127.0.0.1'); // true
5  await isLocalhost('::ffff:127.0.0.1'); // true
6  await isLocalhost('192.168.0.12'); // true
7  await isLocalhost('192.168.0.12', true); // true only if the local machine has an interface with that address
8  await isLocalhost('184.55.123.2'); // false
9
10  await isLocalhost('tino.local'); // true
11  await isLocalhost('localhost'); // true
12  await isLocalhost('microsoft.com'); // false
13})();

Caveats

Doesn't work with internationalized (RFC 3492 or RFC 5891) domain names. If you need that please use wonderful Punycode.js to convert the string before passing to this library:

1const isLocalhost = require('is-localhost-ip');
2const punycode = require('punycode');
3
4(async () => {
5  await isLocalhost(punycode.toASCII('свобода.рф')); // false
6  await isLocalhost(punycode.toASCII('私の.家')); // true
7})();
