What country are you in? How we find out on our web site

And our Traffic Watch Page lets us see the worldwide spread of visitors to our site too.
The database for this is not a small one - there's no easy algorithm that we can use to take an IP address (or any other part of a request to our server) and convert it into a zone or country - the database as a whole is over 1 Mb in size. And it has to be updated from time to time. Rather than try to do the job ourselves, we use the excellent Maxmind database which you'll find at http://www.maxmind.com/app/geoip_country under their flavour of the GPL License. 'Under the license agreement, all advertising materials and documentation mentioning features or use of this database must display the following acknowledgment: "This product includes GeoLite data created by MaxMind, available from http://www.maxmind.com/"'.
The results are claimed to be 98% accurate, and the circumstantial evidence that we have world tend to confirm that. We update regularly (though not every month, as Maxmind do), and we allow our users through our accessibility page to switch their country. I'll never forget a call from Gothenburg in Sweden made to our UK office ... which was to enquire about booking a public course which ended up running in Dublin, Ireland ...
