The answer to the question depends on what you want to do.
If you want your local systems to be able to use the DNS server (as a local concentrator or cache server, or to locally serve your own internal DNS information), then it doesn't matter what IP address it has as long as your local systems can find it. In this scenario you'd have a private network behind a firewall, and the firewall would manage connections to the internet.
If you want systems on the internet to do lookups against your DNS server (ie if you are going to try to host your own DNS domain), the answer is no -- the internet needs to know where your DNS server is before it can use it.
