Classless in-addr.arpa delegation problem

[Kevin Darcy]

Well, you got the delegation and CNAMEs right, but you forgot the NS(es)
for the zone itself! Every zone needs at least 1 NS record for itself,
otherwise technically it isn't even a zone. Assuming
"wintermute.internal" is also the nameserver for 1.168.192.in-addr.arpa,
you could put

    in    ns    wintermute.internal.

just below the SOA record. Don't forget the leading whitespace; that
tells the parser that the owner name is the same as for the previous
line (i.e. "@").

As for the "No default TTL set" warning, here's my boilerplate for that:

By the way, you don't need that $ORIGIN...
