Obscuring this information does you no good. The DNS is by definition a
public database, you're not protecting anyone and you impede folks'
ability to diagnose the problem for you.

Yes. The master has a zone that probably looks like this:

domain.com.  1D IN SOA  ns1.domain.com.  hostmaster.domain.com. (
             2001123000      ; serial
             12H             ; refresh
             1H              ; retry
             2W              ; expiry
             1H )            ; minimum

             IN  NS    ns1.domain.com.
             IN  NS    ns1.otherdomain.com.
www          IN  A     1.2.3.4
@            IN  CNAME www.domain.com.


The LHS of a CNAME cannot own any other records. In this case,
domain.com. also owns the SOA, and is thus a violation. This really is
an FAQ; searching for "CNAME and other data" should have provided you
with thousands of hits explaining it.
