This is completely irrelevant to the original poster's problem. It
does not matter in the slightest where the reverse zone is hosted or
what service is used for that. The problem is that the ISP has not
been able to get the reverse space delegated to them by RIPE. Until
that is done, there's nothing for the ISP to delegate to the customer
and therefore no point in setting up service for the customer's
reverse space. The parent zone of that reverse space hasn't got a
delegation for the zone containing the poster's IP address(es). So all
attempts at reverse lookups of those addresses stop as soon as they
find that null delegations.
