Could someone provide links to sites where IP addresses are grouped by

Thanks in advance!
I haven't done anything but Asia yet, and I've implemented that with a
perl / shell script that downloads the assignments from Apnic, filters
on country code, and builds a shell script to block the nets in a Linux
packet filter chain. It never gets to Postfix.
If you're interested in that approach, I'd be happy to share the code...
Thanks. I would (coming in late to this thread) be interested.
