How to get a user's client IP address in ASP.NET?

Hi,
use this method
private string GetUserIP()
{
return Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? Request.ServerVariables["REMOTE_ADDR"];
}
or
HttpContext.Current.Request.UserHostAddress;
or
HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

To get the IP address of the machine and not the proxy use the following code

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