# MaxMind Geolite2
|
||
|
||
[MaxMind GeoLite2](http://dev.maxmind.com/geoip/geoip2/geolite2/) databases
|
||
are free IP geolocation databases comparable to, but less accurate than,
|
||
MaxMind’s GeoIP2 databases. GeoLite2 databases are updated on the first
|
||
Tuesday of each month.
|
||
|
||
The GeoLite2 databases are distributed under the [Creative Commons
|
||

||
## Country ipset
|
||
|
||
MaxMind distinguishes between several types of country data. The `country` is the country where the IP
|
||
address is located. The `registered_country` is the country in which the IP is registered.
|
||
These two may differ in some cases.
|
||
|
||
They also include a `represented_country` key for some records. This is used when the IP address belongs
|
||
to something like a military base. The `represented_country` is the country that the base represents.
|
||
This can be useful for managing content licensing, among other uses.
|
||
|
||
**In the ipsets generated, an IP subnet is added to all `country`, `registered_country` and `represented_country`
|
||
(of course only when these differ).**
|
||

|
||
## Continent ipsets
|
||
|
||
MaxMind provides the continent each IP subnet is located. Using this information we created the `geolite2/continent_*.netset` ipsets.
|
||
|
||
|
||
## Global providers
|
||
|
||
MaxMind provides two flags for each IP subnet.
|
||
|
||
- `A1` which stands for `is anonymous provider`
|
||
- `A2` which stands for `is satellite provider`
|
||
|
||
Using this information we created two additional ipsets: `geolite2/anonymous.netset` and `geolite2/satellite.netset`.
