Just for the history:
-----------------------
In addition to the simple <domain>.ISO_country_code classification there
are also other ways to get the country origin. But I agree with Martin
(nazdar Martine :) ) there are not so used and tend to be unreliable.
*) Each host belongs to a domain. Each domain has a primary DNS server. You
can query that DNS server for it's geographical location (I don't remember
now the query type). Anyway not all DNS servers has this info available
*) Each host access the internet through an ISP or an Organization. These
providers have assigned several C-Class networks or even B-Class
network(s). Theoretically you could build (:>) a database of IP networks
and it's owner -> for example if a host with IP xxx.xxx.xxx.yyy access your
system you could query your database against the xxx.xxx.xxx network. Once
again ... this just a theoretical approach..
In generall ... IP assignments tend to be a great chaos today so in other
words follow this "rule"
<domain-name>.ISO_country_code -> You know the coutry
<domain-name>.edu | mil -> mostly USA
<domain-name>.org -> chaos
<domain-name>.ISO_country_code.com -> not so used, but when used you know
the country
<domain-name>.com -> another chaos
It's a mess :))
