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

[Georgi Sinapov]

Jim,
You are absolutely right.
I think that the key point here is weather James can accept an outside
visible internal subdomain delegation.
I just make a suggestion that works for me just fine - no internal zone
transfers are possible.
Is using of rfc1918 addresses together with real IP in zone file
prohibited?=20

Best regards,
Georgi Sinapov

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.
