I've written a geoip module from grounds up that operates on a CSV file.
Once you get down to city level or even ISP level IP searches, the
current approach of operating on netmaskable blocks takes up a lot of
memory. Trees seem to be a better option.

Unfortunately, my module is not something that I can release right away
since I store a lot of additional data against each IP range and my code
currently assumes those fields exist. I'll release a cleaner version
once I figure how to refactor the code.
