IP Issue

Hi!

I have searched a lot for this, but haven't found any answer. I have seen many programs and web-applications for geo-locating IP-addresses. I still haven't figured out how to tell in which country the IP-address s h o u l d belong to (geo-locating is 98% accurate as I know. Can anyone here give me some formula to do it yourself or is it possible only for computers?

Thanks.

I presume all these services do is use the RIPE whois database for the IP addresses. More info can be found on their website.

That is the general basis. It is sometimes enhanced by doing a (effective) TraceRT and looking at the locations of points along the way to weed out "anomolies".

For very rough and potentially inaccurate results, you can use something like "Map of the Internet: the IPv4 Space, 2006", at (for example) http://xkcd.com/195/

For much more accurate results, use a database such as that at http://ip.ludost.net/

Note that the whois service is probably not helpful

Thanks.
