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

[Georgi Sinapov]

The original poster's request was no-xfer for that zone.
I am just digging in that direction....

Best regards,
Georgi Sinapov

The obvious exception here is NS records for delegation hints. You
really
should not use 1918 addresses to point to authoritative servers for a
zone, since external resolvers will never go to the right server.

MX records can also have problems in those cases where the MX list
includes 1918 addresses which are also valid mail systems on the remote
network. If a remote mailer tries sending to a 1918 address and delivery
to a local server succeeds (due to overlapping addresses), the mail may
not get delivered if the mailer decides there's a configuration error.
