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 type 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:
string howtogeek = "www.howtogeek.com"; IPAddress[] addresslist = Dns.GetHostAddresses(howtogeek); foreach (IPAddress theaddress in addresslist) { Console.WriteLine(theaddress.ToString()); }
This was tested in C# 2.0.

Good morning.
When I use the Get IP Address from DNS Hostname in C# code, it does pull in the IP Address: 208.43.115.82, but when I step through the code, I am getting an AddressList[0].ScopeId threw an exception of type System.Net.Sockets.SocketException.
I am using VS 2008, C#, and 3.5. Any suggestions? WHEELS
