Can you give me any details?
The only thing I can think of that has to be tied down today is
the IP address of the master server. Everything else, including the
secondaries, can be mobile, and changed on the fly with dynamic
updates. The only piece of infrastructure that I know of that is
outside of the scope of the DNS protocol is the configuration file
syntax (either named.boot or named.conf) whereby the secondary
specifies the IP address(es) from which they will pull copies of the
zone(s) they are to serve.
If I'm wrong, I'd sincerely like to have this explained to me in
detail, and you're an ideal person to do that.
