Answer 1

You can use this method to get the IP address of the client machine.

public static String GetIP()
{
    String ip = 
        HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

    if (string.IsNullOrEmpty(ip))
    {
        ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
    }

    return ip;
}
