Surely you mean sub*zone* (?)

It's not always possible to arrange one's namespace between static and 
dynamic, oftentimes there are other conventions and taxonomies which 
dictate that "static" data and "dynamic" data must co-exist in the same 
(sub)domain. This is when tools like nsupdate and the Dynamic Update 
capabilities of the Net::DNS Perl module come in handy -- to allow 
maintenance of "static" data in zones which also contain truly "dynamic" 
data, maintained by a DHCP server and/or self-registering Wintel clients 
and/or some other infrastructure component(s).
