ASP.NET中的网站访问者位置

Question

My ASP.NET website needs to know the city and country of the visiting user. I have tried following code:

string ip = HttpContext.Current.Request.UserHostAddress.ToString();

And then making a web request to http://api.hostip.info/get_html.php?ip=ip

This method returns me correct user location in some cases, but when user's ISP has hosted server in other country or city, then instead of giving me user's current city (from where he is browsing the website) it gives me the server hosted location.

How can I get the user's location regardless of where his ISP has hosted the server? Like Google does in Google Maps (where browser asks for permission to share location). Or any other better way?
