There is no such query defined in the DNS standards that asks "what are all the
zones you host?".

But, there's nothing to stop you and your ISP from coming up with some sort of
convention for this. E.g. you could define a zone called "_zones" that only
your box and the master would know about and which would just contain a list of
domains (PTR records, for space efficiency, or TXT records). The master would
update that list every time a zone was added or deleted. Query or zone-transfer
that list periodically, and your box could figure out what zones it should
start slaving or stop slaving.
