Running multiple servers from a single I

I am running windows 2k Adv Server. I want to host 5 web sites from one machine (single IP address). | do not know how to set up DNS along with IIS 5 (Name Servers, Zones, etc). I have not been able to find a book or article that gives me the exact details on setting up my server. What articles I found skip steps, consequently I can never get my server working propertly.
