Geolocation providers usually focus on locating end user devices at the edge of the Internet. But what about the machines that make up the infrastructure in the middle? In this episode, I talk to Chris Amin about RIPE IPmap - an API developed by the RIPE NCC to do geolocate core Internet infrastructure.

The idea behind RIPE IPmap actually goes way back. Emile Aben first presented on it at RIPE 67 in 2013 and there’s an article on RIPE Labs from around the same time. You can see its development over time in this article from Jasper den Hertog and this article from Massimo Candela written during their time at the RIPE NCC.
