Solution 2

Your code will need to examine the IP Packet Header[^] received when the user first connects, then extract the source IP address. If you need the port number as well, you'll have to look at the TCP packet that follows the IP information.

Solution 6

There are couple of ways to get IP address.

HttpContext.Current.Request.UserHostAddress;

or

HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

If you want IP Address of the machine, regardless of the proxy settings, you can go for :

HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR");

Solution 1

You cannot find an IP address without some information. You can send a 'ping' to a remote user, but you need either the machine's IP address or its full internet name.
