	Including the master namserver for the zone?  Presumably also 
including the DHCP server for the zone?

	I'm sorry, I just don't believe that these protocols were 
designed for use where the servers themselves (at least, the master 
servers) were using dynamically assigned IP addresses.  If you're 
going to do that, then you also have to make /etc/resolv.conf 
changeable dynamically, and that too is outside the scope of the DNS 
protocol.

	I'd be interested in reading more about this, but it is my 
understanding that the DNS protocol (and presumably most of the rest 
of the Internet protocols) were designed with certain basic 
assumptions in mind, and one of those core assumptions is that there 
are certain "anchor" machines for certain functions, and these 
machines do not move around or have their IP addresses change, and if 
they do move or have their addresses change, then you need to make 
configuration file changes that are outside the scope of the protocol.
