Both of the delegated nameservers -- ns.inreach.net and dogbert.inreach.com --
are lame for 37.209.209.in-addr.arpa. Yes, you should tell them.

ns2.quitt.net is a delegated nameserver for gaskill.net, but you don't have it
anywhere in your configuration. Either you should define it as a slave zone, or
get your nameserver removed from the delegations. If someone has delegated to
your nameserver without your permission and refuses to change it, and you don't
want to be a slave, then you might consider setting up a master gaskill.net
zone pointing to a porno site, hate-group site, parody site, or whatever, until
they learn the error of their ways. I don't *think* you could be held liable
for that (they're the ones claiming that your nameserver is authoritative,
after all)...
