It's not really programming. Each machine on the Internet has an IP address (those things like 212.159.61.36). A system called DNS (Domain Name Service) converts the names you are used to to these IP addresses. So tty.org.uk is, in fact, 212.159.61.36. You can have lots of names sending to the same IP - which is the "proper" way to do it. Actually I just use the service provided by the people who provide me with the domain. When you type canalplan.eu into your browser it converts it into 194.154.164.82. This is part of the domain registers IP numbers. So your browser goes there and hits a page that says "go to canalplan.tty.org.uk instead"). tty.org.uk is, btw, my brother Steve's machine. So very computery, but not very programmy. It's all the magic that goes on behind the scenes to make the Internet work. I don't understand a lot of the details myself - just enough to make it work!
