You should delegate
1.0.0.0.0.0.0.0.2.3.B.D.0.B.2.0.C.7.6.0.1.0.0.2.IP6.ARPA normally.
This will let everyone in the world find the CNAME records. This
should be done even if you are just doing it for your recursive
clients.
If you don't want A to AAAA mappings to happen then turn off the
DNS64 mapping for everyone on the server.
dns64 2001:67c:2b0:db32:0:1::/96 {
clients { none; }
};
