Ask HN: What do you use to do GeoIP lookups

Don't know how well it compares to MaxMind or other commercial services but http://www.datasciencetoolkit.org/ may be worth looking into.

Is there some reason MaxMind isn't working for you?

I use MaxMind's data locally. I try to use as few remote APIs as possible to minimize disruption if one of them decides to have issues.

This is a bit expensive, to purchase the data I require (http://www.ip2location.com/databases/db5-ip-country-region-c...) costs $349.00, then I have to spinup a server.
