But if I use ping to discover the IP Address of www.alug.org.uk and then type it (http://199.254.168.73) into the browser the PHP4Hosting.com homepage appears rather than the ALUG webpage I was expecting. This confuses me, but is probably simply an unrelated point.
The HTTP protocol includes the name of the host being asked for in the request, as a Host header. Apache's virtual hosting support uses that header to decide which web site to show, as it can have many hostnames, all pointing at the one IP address.
I'm not sure that we're any nearer understanding why only your browser is broken, though.
