Strictly speaking it is legal to use DNAME at the apex of a zone since 
DNAME only redirects descendant domains.

For example:-

251.250.63.in-addr.arpa. IN DNAME rev.cust.example.com.

And in the customer's zone:-
1.rev.cust.example.com. IN PTR ip63-250-251-1.cust.example.com.
ip63-250-251-1.cust.example.com. IN A 63.250.251.1

I do not disagree that in arin region swip is the way to go. Just 
showing that there is MTOWTDI!
