Package Exports

is-localhost-ip

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-localhost-ip) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

is-localhost-ip

Comprehensively checks whether given DNS name or IPv4/IPv6 address belongs to local machine

Main difference from other libraries here is comprehensiveness: we start from simple RegExp checks, then fallbacks DNS resolver (so it works with something like john.dev remapped locally).

Requires Node 10+, 100% code coverage

Installation

npm i is-localhost-ip
yarn add is-localhost-ip

Example

const isLocalhost = require('is-localhost-ip');

(async () => {

    await isLocalhost("127.0.0.1"); // true

    await isLocalhost("192.168.0.12"); // true
    await isLocalhost("184.55.123.2"); // false

    await isLocalhost("tino.local"); // true
    await isLocalhost("localhost"); // true
    await isLocalhost("microsoft.com"); // false
