Of course you can write whatever you like in any file you have write
permission to, but if you meant to ask "is this legal in the DNS?" the
answer can hardly be yes.

This was up on BIND9-Users just yesterday (April 6), and Mark Andrews
contributed "Nameservers cannot be CNAMES." I have trouble seeing how
such a statement could possibly be misunderstood.

In general, RRs which reference other RRs should reference the
canonical name and not an alias.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
