        {
            string IP4Address = String.Empty;


            foreach (IPAddress IPA in Dns.GetHostAddresses(System.Web.HttpContext.Current.Request.UserHostAddress))
            {
                if (IPA.AddressFamily.ToString() == "InterNetwork")
                {
                    IP4Address = IPA.ToString();
                    break;
                }
            }

            if (IP4Address != String.Empty)
            {
                return IP4Address;
            }

            foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
