	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.
