Probably a *very* stupid question....

The server should round-robin by default unless it's very old (pre-4.9,
I think) or relatively new (8.2.x) with an rrset-order option specifying
"fixed" order.

Why would you want to round-robin PTR's? Most client resolvers only look at
the first PTR in a list, so if the ordering behavior is anything other than
"fixed" the end result is a perceived "inconsistency" in answers from the
nameserver. In our internal DNS, we don't allow multiple PTR's.
