The file contains IPv4 address ranges to Country mappings.

It is used for determining the country that an IP address is in.
This as several configuration commands allow avoiding/requesting a
specific country.

(Yes, these kind of mappings are not 100% accurate and due to the
dynamics of the Internet might be wrong too, but it is 'good enough')

The numbers decimal representations of an IP address.
