Usually you can hit ARIN up and they'll point you at the correct registry for the IP if they're not it. This isn't fool-proof by any means of course. for instance, 195.71.90.10 % whois -h whois.arin.net 195.71.90.10 [snip] ReferralServer: whois://whois.ripe.net [snip] whois -h whois.ripe.net 195.71.90.10 [snip] inetnum: 195.71.0.0 - 195.71.255.255 netname: DE-MEDIAWAYS-970127 descr: PROVIDER Local Registry descr: Telefonica Deutschland GmbH country: DE [snip] The reverse doesn't really make sense unless I'm misunderstanding you - there's no direct correlation of network address blocks to specific countries that I know of, although you might be able to try different queries against the big ones (ripe.net, apnic.net, arin.net, etc) for particular countries (like resolving www.de to the above example IP) -- James Manning <http://www.sublogic.com/james/> GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4 -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
