Intranet Server

Hi all, I'm not sure if I should ask this question in this group, but since I'm using PHP in the process, I thought someone might be able to help me. Anyways. I'm in charge of creating an intranet webzine for my school and I've been working on the server-side for a while. I want to know if there is anyway that I could map the IP of the server (internal IP on the local network) with a name like http://intranet/ and have sub ips like http://math.intranet/. I tried reading about DNS, but it seems that it only works for internet addresses and involves registrations of a domain name. Has anyone done this before? If yes, what are the system requirements and is there anywhere that I can learn how to do it. Thanks in advance, Ali _________________________________________________________ Do You Yahoo!?
