The "ip" library is a Node.js library that provides utility functions for working with IP addresses. It provides functions for parsing, validating, and converting IP addresses between different formats.

The "ip" library provides a simple and easy-to-use interface for working with IP addresses in Node.js. It can be useful in a variety of contexts, such as when creating a network-related application or when working with IP addresses in a web application.

Example Use


const ip = require('ip');

// check IP validity:
console.log(ip.isV4Format('192.168.1.1')); // true
console.log(ip.isV4Format('2001:0db8:85a3:0000:0000:8a2e:0370:7334')); // false

// check subnets
console.log(ip.cidrSubnet('192.168.1.1/24')); // { networkAddress: '192.168.1.0', broadcastAddress: '192.168.1.255' }
console.log(ip.not('255.255.255.255')); // '0.0.0.0'
