Question

How do you get the IP address of the web/application server in .NET? Not the client IP address, but the server IP address.

I just found something about server variables.

You probably want something like the following code, to get all IP addresses of the current machine. However it won’t tell you which network adaptor (and thus IP address) a particular request came in on, if you have more than one.

   String strHostName = Dns.GetHostName();
   Console.WriteLine("Host Name: " + strHostName);

   // Find host by name
   IPHostEntry iphostentry = Dns.GetHostByName(strHostName);

   // Enumerate IP addresses
   foreach(IPAddress ipaddress in iphostentry.AddressList)
   {
       Console.WriteLine(ipaddress.ToString());
   }
