No, I already have a couple webservers.
www.classicserver.net
Right now I have the domain pointed with DNS to a CPanel (hosting) account that I pay for. Then in CPanel, I redirect it to my IP and port.
What I want is another machine of my own to be a DNS server. First, I will have to edit my domain registration info to use the name of my personal DNS server. Then when a browser types
www.classicserver.net it will contact my DNS server and my DNS server will say "oh, I know the IP for that domain, here ya go" and then the browser will say "okay great, I'll go ahead and load that IP"
I have the software installed, I just don't know much about it. I don't know what name to give my DNS server and stuff like that.
