Simple Example

// Convert IPv4 string to demical & check IP is bogon.
import IP from '@wnynya/ip'; // ESM

const ip = new IP('127.0.0.1');

console.log(ip.toDemical()); // true
console.log(ip.isBogon()); // true

console.log(ip.in(new IP('127.0.0.1', '127.0.0.255'))); // true
console.log(ip.in(new IP('127.0.1.0/24'))); // false
