That was my point. On the other hand, Applications people (like
myself) that work with directory services and similar see risk for
data corruption issues and extremely hard to debug chasing of RRs if
the DNAME has a target outside the zone the record resides in. I.e.
if the DNAME reference a record in the same zone the DNAME resides
in, one is safe for these kind of problems. If not, one can end up in
situations that should be studied a bit more.
