Perfectly kosher.
They need to delegate zone "8.57.105.216.in-addr.arpa" to your name
server - would that be dante.plover.org?
Once this is done, you need to create a zone "8.57.105.216.in-addr.arpa"
on your name server. It will contain a $TTL, an SOA, the NS records,
and
9 IN PTR name1.domain.
10 IN PTR name2.domain.
(etc.)
Ah - I see you've already done this. ;-)
