use the following code to get ip address using DNS settin

Private string GetIP()
string strHostName = "";
strHostName = System.Net.Dns.GetHostName();

IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);

IPAddress[] addr = ipEntry.AddressList;

return addr[addr.Length-1].ToString();


The IP Address can be retreived in the following ways.

String str = HttpContext.Current.Request.UserHostAddress;



The REMOTE_ADDR usually provides the IP Address of the Internet Service Provider in some cases.As a result it may be required to test with HTTP_X_FORWARDED_FOR to get the real IP Address.This might also contain an array of IP addresses when connected through proxies.

Eg : Request.ServerVariables(”HTTP_X_FORWARDED_FOR”);

and check to see if it returns an Empty and then retreive the corresponding IP Address using REMOTE_ADDR.

void getClientInfo()
  string RemoteIp = Request.UserHostAddress.ToString();
  string DNSName = Request.UserHostName;
  string user = HttpContext.Current.Request.UserHostAddress;
  Response.Write("</br>Remote Ip:" + RemoteIp);
  Response.Write("</br>DNS Name :" + RemoteIp);
  Response.Write("</br>" + Environment.MachineName.ToString());
  Response.Write("</br>  User:" + user.ToString());
  Response.Write("</br>" + Environment.UserName.ToString());
  Response.Write("</br>" + System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString());
