Answer 1

HttpContext.Current.Request.UserHostAddress

This does not attempt to take proxies into account. You can use for this Request.ServerVariables["HTTP_X_FORWARDED_FOR"]. However, make sure that you do not blindly trust this, as it can be faked. It’s better to keep a whitelist of the IP addresses you trust.

Answer 2

    String clientIP = 
(HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]==null)?
HttpContext.Current.Request.UserHostAddress:
HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
