ip2country

A python module for looking up the country in which a given IP address resides.

Features/quirks:

Maintains a cache of IP address allocations, downloading the table from the APNIC database only if the cached version is missing or stale
Fast lookup - builds optimal lookup tables from the cached APNIC file
Ideal for situations where you want to do frequent lookups within your program
Just run the file under Python to get an interactive demo

There's a simple demo at the bottom of the file, which you can invoke by simply running the file with the python interpreter

Here's an example:

>>> import ip2country
>>> ip2c = ip2country.IP2Country(verbose=1)
>>> ip2c.lookup("202.27.184.3")
