You can put the common data in a $INCLUDE file.  However, a side effect of
this is that "ndc reload" will take longer, because any file that uses
$INCLUDE is always reread (named normally remembers the modification time
of the db file for a zone, so it only needs to reload the ones that have
changed, but if a db file uses $INCLUDE it doesn't remember the
modification times of all the files that it depends on, so it assumes the
worst).

But if there are only 500 domains and they're pretty small, this should
only take a couple of minutes.

Another solution is to use a script to generate your zone files.
