That's what DNAME does, regardless of where in the DNS tree it is.  It
redirects the subtree under the DNAME but not name where the DNAME is.
You can put other RRs (except CNAME of course) at the same name as the
DNAME.

If it does what you want, sure.  In the frequent case that it doesn't,
you need to do something else.

the DNAME already recommended by Dave Warren is what you want:

xyz.gov.in. DNAME   xyz.in.

There are a variety of ways to deal with this
but in practice:


another possibility is to include the same file to zone files for both
domains as Leonard Mills recommended.


is the easiest way to do it if you're using BIND.

Except that DNAME only applies to names under xyz.gov.in, not to
xyz.gov.in itself.  There are a variety of ways to deal with this

not like this. Note that:

- "*" in source address will apply for all non-existing domains, which means,
any domain already existing in xyz.gov.in will NOT be affected.
- "*" in destination will not work as wildcard.

the DNAME already recommended by Dave Warren is what you want:

xyz.gov.in. DNAME   xyz.in.

another possibility is to include the same file to zone files for both
domains as Leonard Mills recommended.  This way you can also have other,
different records in both domains, good when you want transition from one
domain to another.

RRL was added to the BIND 9.9 branch late, in release 9.9.3.

 

Ordinarily, it's our policy only to add new features in 9.x.0 releases.

We felt that this feature was important enough to make an exception to our
usual rule, but since code changes of that size always introduce a risk of
destabilization, we decided to make it a compile-time option: those who want
RRL can get it; those who don't can skip it.

 

RRL will be enabled by default in 9.10.0.

That sounds roughly like a possible use for a DNAME record, I believe.

Re: Query regardign CNAME

Not with a CNAME, but you can get what you want with two zone definitions and 
one $INCLUDE directive in each zone below the appropriate $ORIGIN statements.  
That way will allow all of your, for example,  RRs to be the same in each 
domain but only be maintained in one entry.
