Big Box of Datasets

This box is a bit different. It contains links to several different datasets that might be useful to programmers.

IP2Location Lite - A free(!) dataset that allows you to work out where in the world an IP address is located. Has both IPv4 and IPv6 datasets available!
Joe Reynolds' wordlists - A collection of various (free!) wordlists for all occasions.
DevData - Convert datasets so they're ready for inclusion in several programming languages. Comes with a few datasets inbuilt, but you can addd your own.
