OTOH, it might make a good feature (and eventually maybe a BCP) to block PTR queries for 1918 space from going to the roots and TLD servers.
I added something like this to our binds that handle recursive queries. Is there any reason distros (or ISC) couldn't make this a part of the "default config"? zone "168.192.in-addr.arpa" { type master; file "sink"; }; zone "10.in-addr.arpa" { type master; file "sink"; }; ... other similar zones clipped sink is just @ IN SOA localhost. root.localhost.
