            {
                try
                {
                    var temp = webClient.DownloadString("http://iframe.ip138.com/ic.asp");
                    var ip = Regex.Match(temp, @"\[(?<ip>\d+\.\d+\.\d+\.\d+)]").Groups["ip"].Value;
                    return !string.IsNullOrEmpty(ip) ? ip : null;
                }
                catch (Exception ex)
