What's wrong with just Request.ServerVariables("REMOTE_ADDR") ..?

C#

foreach (var item in Dns.GetHostEntry(HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]).AddressList)
                {
                    if (item.AddressFamily == AddressFamily.InterNetwork)
                    {
                        IP4Address = item.ToString();
                        break;
                    }
                }
