Just out of curiosity: how do you plan to find out server locations (beyond the obvious top-level domain -> country heuristics)?

Some also have location in the TXT field in DNS (Sometimes called an ICBM record). I think 'xt(raceroute)' uses this.
Actually, this is not a property of DNS. Blocks of IP numbers are assigned to specific countries, who give them out to their ISPs. The top-level rules are in http://www.iana.org/assignments/ipv4-address-space http://www.faqs.org/rfcs/rfc1466.html but there is not much detail there. Google points to various sites that have collected much more information and made it available for free or for pay. I don't know much about them. -Yitz
