Since blackholes.us went away, the only other one I have found semi-reliable is Country IP Blocks at http://www.countryipblocks.net -- Larry Smith lesmith@ecsis.net
http://countries.nerd.dk/ publishes files that can be used in some form of an RBL that covers most of this as well. I use this for a geolocated DNS system and it works well. I have actually manually referenced this to find where a specific block is from. -----Original Message----- From: Larry Smith [mailto:lesmith@ecsis.net] Sent: Wednesday, May 12, 2010 10:22 AM To: nanog@nanog.org Subject: Re: CIDR blocks, by country On Wed May 12 2010 11:09, Michael Holstein wrote:

I found that list to be out-of-date and slow to change (when errors were pointed out). I ended up taking the Maxmind free database and writing a perl DNS server to feed it. The free database is updated once a month and that is good enough for my uses. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
Maxmind or Quova offer a commercial database if that’s what you need. Maxmind also do a less frequently updated free version.

For the whole APNIC: http://www.apnic.net/publications/research-and-insights/ip-address-trends/ap... ftp://ftp.apnic.net/apnic/stats/ carries raw data files updated daily for all allocations in a delimited file format. you may have to do some sorting, what i do is put it in a mysql database and do selects per country of interest. hth.

See: http://www.bgpmon.net/IPtoCountry.txt This list is generated once a day. It should contain all prefixes in the BGP table of which it was able to determine the country. The list contains both IPv4 as well as IPv6 prefixes.
If it matters, I'm specifically interested APNIC and AFRNIC.
I can supply similar lists based on country or continents if there's enough interest. Cheers, Andree

I've found that ipdeny.com publishes an extensive and frequently-updated list of netblocks associated with about 225 countries. Also, see: http://www.okean.com/koreacidr.txt http://www.okean.com/chinacidr.txt for blocks for those two countries. I've not tried to make an assessment of which of these two resources is more accurate WRT cn and kr, but they do exhibit minor differences from time to time. ---Rsk
