Question

Getting the IP address of server in ASP.NET?

How do I get the IP address of the server that calls my ASP.NET page? I have seen stuff about a Response object, but am very new at c#. Thanks a ton.

This should work: 

 //this gets the ip address of the server pc

  public string GetIPAddress()
  {
     IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName()); // `Dns.Resolve()` method is deprecated.
     IPAddress ipAddress = ipHostInfo.AddressList[0];

     return ipAddress.ToString();
  }

OR 

 //while this gets the ip address of the visitor making the call
  HttpContext.Current.Request.UserHostAddress;

Request.ServerVariables["LOCAL_ADDR"];

This gives the IP the request came in on for multi-homed servers
