How to request rDNS from my ISP?

[Kevin Darcy]

You have to do things their way, since they're the ones delegating the 
zone to you from their particular branch of the in-addr.arpa tree.

What zone, in particular, are they saying you're not authoritative for? 
Set up that zone and populate it.

                                                                         
                        - Kevin
