I would like to create custom nameservers for a Server i just purchased. I seem to be getting unclear messages from my Host & Domain registrar on what the process should be.

I have rockitwebhosting.net registered. i would like to be able to provide ns1.rockitwebhosting.net & ns2.rockitwebhosting.net etc. to clients to use as nameservers.

i have no other servers hosting nor do i have a DNS created somewhere's else? what should be the process in getting these created?
