Resolve a Hostname to an IP Address

Demonstrates Socket.DnsLookup, which resolves a hostname and returns one numeric IP address.

Background. A maxWaitMs of 0 waits indefinitely; a positive value bounds the wait. Resolved results may be served from Chilkat's process-wide DNS cache.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var socket = new CkSocket();

//  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
var ipAddress = socket.DnsLookup("example.com",5000);
if (socket.LastMethodSuccess == false) {
    console.log(socket.LastErrorText);
    return;
}

console.log("Resolved IP address: " + ipAddress);
