Check if an IP is a bogon
npm install bogon
const bogon = require('bogon')
console.log(bogon('192.168.0.1')) // true
console.log(bogon('8.8.8.8')) // false
As a utility it also exposes an isPrivate helper
to detect if a bogon IP is a private IP address on a local network.
console.log(bogon.isPrivate('192.168.0.1')) // true
console.log(bogon('224.0.1.1')) // true
console.log(bogon.isPrivate('224.0.1.1')) // false
