Either that, or they can add the entry for you.  But all reverse DNS
requests will go to them, so they *must* do something on their end to let
other DNS servers know that the reverse DNS entry exists, or to go to your
DNS server.

They should take care of that for you (either by adding the reverse DNS
entry themselves, or by instructing you how to do classless reverse DNS).
