Try this to get IP

HttpContext.Current.Request.UserHostAddress; 
or 
HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
or
HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

Store some where in database..now for every time on Request for survey you can lookup in database that it is exist or not
