Well i guess i can give you some pointers without calling you an idiot.

- First go into basic whm setup >
Then go to primary nameserver
Then use a domain you already own and put this term behind it "ns1" and "ns2" for example:
ns1.domain.com < Primary Nameserver
ns2.domain.com < Secondary Nameserver

Then click the button that says "assign ip" and note that ip down!
Then go to your registrar where your domain is registered and look for FAQS on how to make custom nameservers using the ips you have.


And about hosting multiplke websites:

You can host as many websites as you want on 1 ip, its called being on a shared ip.


That should do it i think
