[bitfolk] Bind9 & Nameservers

Hi guys, 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 This is what I have no idea about: -Do these subdomains have to be on different servers, or just different IP's? Can they even use the same IP? -If they need to be different, can my hosting server be on 1.2.3.4 if my nameservers are: 1.2.3.4 and 5.6.7.8 I have followed this: https://help.ubuntu.com/10.04/serverguide/C/dns-configuration.html in order to set up my first nameserver, and it will now ping example.com if I set the resolv.conf to use itself. If I set turasmara.com to use that nameserver, and ping it from my home box I do not get anything. However if I ping it from the VPS I get: root@hostinghaven:~# ping turasmara.com PING turasmara.com (1.2.3.4) 56(84) bytes of data. 64 bytes from www.domainname.com (1.2.3.4): icmp_seq=1 ttl=64 time=0.018 ms What have I done wrong...and what do I till need to do to get this to work? Thank you, Daniel
