   BIND's built-in automatic empty zones are fundamentally different 
from "normal" zones (those loaded from a zone database or transfer). 
The code handles them as a special case.  It's not just a zone file 
that's hard-coded into the program.

   If you really want to get into gory details, grep for and 
DNS_ZONEOPT_AUTOEMPTY and DNS_ZONESTATE_AUTOMATIC in the BIND source 
code.  But this is a level of detail you almost certainly do not need.  :-)

   The following article has more information about the auto zones 
(although it does not get into the implementation, just purpose and 
configuration):
