I've often seen sites (usually ISPs) which once you have an account, give you a web site on their server with the URL www.myname.ispname.com
I beleive this is something to do with setting up DNS on the server, but I really haven't a clue.
Is it possible to do this using IIS so that I can have various areas in my site linked via a URL like www.area1.mysite.com; and if so - how do I do this?
Incidentally, I know setting a host header name up will allow me to respond to different server names from the same server, however this means that each server name has to be registered separately.
I'd really like some step by step instructions if possible, and I can up the points if it gets a bit involved.
