Example: This example authenticating the validity of the IP address format of the String using the Library Functions.
const ip = require('ip-address');
function checkIpAdress(ipAddress) {
try {
const parsed = new ip.Address6(ipAddress);
return parsed.isValid() || new ip.Address4(ipAddress).isValid();
} catch (e) {
return false;
