Note: This add-on uses a free third party geolocation database service, to avoid you having to store a massive IP geolocation database on your server. No guarantee is provided that all the many currently free third party geolocation database services won't one day cease service. The geolocation database JSON request URL is set with a default, but is definable by you via the Admin Control Panel if you want to change to another service.
