First, it is awesome there's a widget to get your IP Address - and you went the extra mile to support dual-stack and perform a Geo-lookup! So this is only a nitpick.
It would be nice if the results of the widget weren't cached locally - or otherwise allow a user to manually refresh the widget, e.g.,
It is not completely visible to end-users that the results are ultimately cached, nor is it easy for end-users to clear their local cache (keeping cookies).
