This micro library handles the GeoIP lookups, mappings from IP addresses to country codes.

It uses the free ip2location lite database, which is available from https://lite.ip2location.com/database/ip-country under a CC-BY-SA 4.0 license.

It also handles mapping from IP to ASN (Autonomous System Number) using data from apnic.net.
