   True. But that's why most large organisations use split DNS so that
   their public face can be kept discrete (and discreet!) from whatever
   they do internally. The non-sensitive data can go on the outside and
   the company-confidential stuff stays on the inside. This is a policy
   issue anyway. It's not support for a technical argument in facour of
   restricting zone transfers. If data is supposed to be private, it
   shouldn't be in a public data service like the DNS!

I never said it was the only solution.  It's a popular, simple solution.
