Get IP Address from DNS Hostname in C#

A frequent task when designing applications that work with TCP/IP and the internet is to lookup an IP address from a hostname.

It’s much easier for users to deal with the hostname than having to jot down in an IP address.

First you’ll add the System.Net namespace to your using section:

using System.Net;

Example of code to get address from hostname:

IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek);

foreach (IPAddress theaddress in addresslist)

{

Console.WriteLine(theaddress.ToString());

}

This was tested in C# 2.0.
