In most cases, I set up new master zones for each domain I am going to
shanghai. Thus I have a zone for 'ispyourkeyboard.example.' and put in
a wildcard for it grab all things.. related to it. I make sure that
the internal DNS servers are 'authoritative' for these miscreant
zones... and that internal boxes aren't able to go to other DNS
