Not sure if the geoblocker DB is not updated, or a problem with geoblocker and ipv6 addresses that require a 64-bit OS:
For this service to work with IPv6 you need at least a 64 bit system. If this is not fulfilled IPv6 addresses will be always returned as ‘AA: Country Not Found’ and the database will not be filled with IPv6 data (starting with version 0.5.0). If you change your system make sure to update the DB again.
