CODE1

Using this code i am getting IP 100.43.0.212

of my server where i have uploaded my website

private void IPAddress()
        {
            IPHostEntry host;
            string localIP = "?";
            host = Dns.GetHostEntry(Dns.GetHostName());

            foreach (IPAddress ip in host.AddressList)
            {
                if (ip.AddressFamily.ToString() == "InterNetwork")
                {
                    localIP = ip.ToString();
                    TxtExt.Text = localIP;
                }
            }
        }

Using thic code i am getting 87.101.226.125 which is unknown

<script type="text/javascript">
         window.onload = function () {
             var script = document.createElement("script");
             script.type = "text/javascript";
             script.src = "http://www.telize.com/jsonip?callback=DisplayIP";
             document.getElementsByTagName("head")[0].appendChild(script);
         };
         function DisplayIP(response) {
             document.getElementById("ipaddress").innerHTML = "Your IP Address is " + response.ip;
         }
</script>

使用此代码，我正在获取我的代理服务器100.43.100.101的IP

using this code i am getting IP of my proxy server 100.43.100.101

public string GetIP4Address()
  {
      string IP4Address = String.Empty;

      foreach (IPAddress IPA in Dns.GetHostAddresses(this.Request.ServerVariables["REMOTE_ADDR"].ToString()))
      {
          if (IPA.AddressFamily.ToString() == "InterNetwork")
          {
              IP4Address = IPA.ToString();
              break;
          }
      }

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

      foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
      {
          if (IPA.AddressFamily.ToString() == "InterNetwork")
          {
              IP4Address = IPA.ToString();
              break;
          }
      }

      return IP4Address;

  }

但是我的本地IP地址是100.43.1.16

but My local IP address is 100.43.1.16

推荐答案

string address = request.UserHostAddress;

<script type="text/javascript" src="Scripts/jquery-1.6.2.js"></script>
