The GeoIP Redirect extension uses an external database of IP addresses and their geographical locations from the third-party service MaxMind. Our module uses maxmind-db Reader to read the database, and it uses the current MaxMind DB. MaxMind has different types of databases: a free and a paid one. You can use the GeoIP Redirect module after installation without additional payment.
Since our module uses maxmind-db Reader to read the database, you may select the most suitable database according to your requirements - our module should work with it.
