A BIND8 server supports a maximum of around 16 million zones, assuming
your OS allows the name server to use enough VM to hold that number of
zones. I'm not aware of anyone running servers that have anything like
that many zones, though I've heard of a few organisations - big ISPs,
telcos, etc - that have 100-500k zones on their name servers.
