I released geoip today. It's a Racket library for working with MaxMind's geolocation databases. It's got a tiny API surface (3 functions!), but it should be useful to anyone needing to do geolocation in Racket. As always, check it out and let me know what you think!
BTW, I streamed the whole process on Twitch so, if that's your thing, you can check out the recordings here.
