smart_ip.module in Smart IP 7.2
Same filename and directory in other branches
Determines country, geo location (longitude/latitude), region, city and postal code of the user, based on IP address
This module uses the IP address that a user is connected from to extract the location information where the user is located. This method is not foolproof, because a user may connect through an anonymizing proxy, or may be in an unusual case, such as getting service from a neighboring country, or using an IP block leased from a company in another country. Additionaly, users accessing a server on a local network may be using an IP that is not assigned to any country (e.g. 192.168.x.x).
