Proper response of reverse lookup private IPs

[Kevin Darcy]

The delegated nameservers for 10.in-addr.arpa on the Internet are both called
"blackhole": can you guess why?

If you want 10.*.*.* reverse-lookups to work sanely for your clients, set up
a 10.in-addr.arpa master zone on your nameserver.
