Looking for way to mark a zone no-xfer for a sub-domain .

He *has* to do split DNS - discrete internal and external copies of
his zone - if he doesn't want the outside world to even know about the
presence of the delegated zone. Whether the name server(s) for that
zone are reachable from the outside or not doesn't matter. There would
still be NS records for the delegation in the parent zone. If he can
live with that, then split DNS is not necessary. If not, he needs to
have two versions of that parent zone: one for the outside that
doesn't contain the delegation and one for the inside that does. I
didn't make that clear in my earlier posting.
