Help to understand principle of accessing ISPCP OMEGA

[dexit]

ya i get it dont get me wrong, but couldnt you just said, YEs you need to buy a domain name, target it to your server IP

By the way http://MY-IP.TLD GETS ME - 404 !!! I have the /var/www/ folder full of files etc, but as i remember the vhost is responsible for it, tried to fixing it, didnt work, Thats why im asking...

EDIT

So ill clear up, and tell you what i understood.
1. I go, buy a domain (or i own one)
2. following this link http://support.godaddy.com/help/668
3. pointing the ns1 and ns2 to my servers ip right ?
4. Then when its all ready after 24-48h, I setup my ISPCP server, and if the iP for server is the same as ns BIND will control my domain, or in other words, ill be my own DOmain hoster ^_^
5. When installing when the installation asks me for the host, i enter panel.domain.tld or just domain.tld ?, and it will add a ZONE right ?

afterwards it should work... is this the right course of action ?
