Are you asking from a "best practices" point of view or an RFC point of
view?
RFC 2181 "Clarifications to the DNS Specification" is quite explicit in
section 10.2. "PTR records"
Confusion about canonical names has lead to a belief that a PTR
record should have exactly one RR in its RRSet. This is incorrect,
the relevant section of RFC1034 (section 3.6.2) indicates that the
value of a PTR record should be a canonical name. That is, it should
not be an alias. There is no implication in that section that only
one PTR record is permitted for a name. No such restriction should
be inferred.
