This "in this example anything not in 192.168.1" should more correctly
read "in this example anything not in 192.168.1 but in 192.168".

This is also useful if you use Unbound as a resolver. It will prevent
such PTR queries from being leaked to the Internet and requiring an
answer from the arin servers.
