Just looking around at CPAN

http://search.cpan.org/~tjmather/Geo-IP-1.27/
but it seems to be dependent on databases supplied by
     http://www.maxmind.com/app/products
and so is a commercial product?


http://search.cpan.org/~location/Geo-IP2Location-2.00/
but the readme notes
   The complete database is available at http://www.ip2location.com 
under subscription package.
so it is another frontend to commercial offering.


http://search.cpan.org/~gmpassos/Geo-IPfree-0.2/
readme says "See CPAN for updates..." so naturally the latest update 
was March 2003:w


http://search.cpan.org/~tjmather/Geo-IP-PurePerl-1.18/
The IP address to country database is available for free, updated monthly:
   <http://www.maxmind.com/download/geoip/database/>http://www.maxmind.com/download/geoip/database/

 From the same guy athttp://sourceforge.net/projects/geoip/
talks about GeoLite databases "that are not as accurate"
     http://www.maxmind.com/app/geolitecity
but it's down to the city level, that's good, right?


Look up of country is apparently easier to get data for . . .

http://search.cpan.org/~nwetters/IP-Country-2.23/
Free
I'm not sure if this is required?
http://search.cpan.org/~nwetters/IP-Country-Data-0.01/


http://search.cpan.org/~nwetters/IP-Country-DNSBL-1.02/
Dynamic


and that one link to SourceForge is an idea of where else to look?
