In fact, there was a move on a while back to not use 'www' and instead use 'web' or 'w3'. (You can see how far it got ;-). at the Phoenix Linux User's group, we don't use www (even though we could, and maybe should at least ALLOW it (http://plug.phoenix.az.us/)). My home machine has lots of names, all by the magic of dns. (a dig of descomp.com should turn up www, mail, and some others, all pointing to the same place - my linux firewall ;-) So, back to the original question. the difference between www.foo.com and foo.com is that www.foo.com is it is one level deeper on the DNS tree than a machine at foo.com, and if you have both www.foo.com and foo.com, then technically foo.com is a domain and www.foo.com is a machine - however often you'll see foo.com resolving to an address (the same one as for www.foo.com makes sense ;-) There, now I bet its clear as mud! (Where's that DNS Howto reference.. hmm... rats, I had it somewhere... hmm, well go look up DNS HOWTO using you favorite search engine ;-) rc Rusty E.
