ok, have a new box just setup running RH 3E and currently one IP address. Evidently my DNS is configured as a caching server. All of my domains are registered at opensrs which doesn't allow for foreign nameservers. So, when I change the nameservers for my domain, I have to create names like ns1.domain1.com, ns2.domain1.com for the first domain, and of course ns1.domain2.com, ns2.domain2.com for the second. All point to the same IP address.
First newbie question - should I have more than one IP address on the server? should I have 2 and have ns1.domain1.com point to one and ns2.domain1.com point to the second.
Second question, should I move away from opensrs and go somewhere else (like enom?) where I don't have to specify nameservers that derive from the domain name registered at opensrs. Can I have a nameserver on my machine that answers for all the domains that are currently hosted on it?
