C library for the MaxMind DB file format

The libmaxminddb library provides a C library for reading
MaxMind DB files, including the GeoIP2 databases from MaxMind.
This is a custom binary format designed to facilitate fast
lookups of IP addresses while allowing for great flexibility
in the type of data associated with an address.

The MaxMind DB format is an open format. The spec is available
