> Free IP Geolocation API - lookup any IP address. Provides geolocation data based on the input IPv4/IPv6 address or domain name

Where does one get a geo location for an IP address from?

In this particular case they seem to pull from https://www.maxmind.com/en/home

There's a bunch of IP/GPS and physical address lookup sites, services, and databases out there.
