There is no inbuilt method to that. There are web-services on the internet that will provide such mapping. Such databases "GeoIP databases" are also available for local use.

But it would be best to subscribe to an updated web-service and use that to get the location. Google's Client Location API 's should help you here.

Some modern browsers will send you the users location. You can use that. But since this is not followed by all browsers, it is not reliable. You can check out the Geo Location API provided by w3.org.
