There are no per-zone or per-name limits in BIND, AFAIK.  There are some
practical limits, having to do with the size of DNS packets.  For instance,
the root nameservers used to be in lots of different domains, but this
caused the reply packet containing the list to overflow the 500-byte UDP
limit when there were about 10 servers, so they created the
ROOT-SERVERS.NET domain so that they could take advantage of DNS's
compression mechanism.
