Hi guys,It doesn't answer your question, but having dabbled in a similar area myself I did arrive at some conclusions:
I am planning to resell hosting accounts on my VPS to businesses as part of a web design and programming job that I do now. However, I appear to be having some problems with bind9, and setting up my own nameservers. I originally thought that a domain translates to an IP and that was the end of it.
This is what I know so far:-I need 2 subdomains, ns1.mydomain.com and ns2.mydomain.com
