Not good. Your provider has delegated the reverse resolution for the
single address 212.204.192.51 to ns1.jdimedia.nl as a zone of its
own, so the server ns1.jdimedia.nl should rather be configured like
this:

zone "51.192.204.212.in-addr.arpa" {
   type master;
   file "zones/own/51.192.204.212";
};

And in the zone file:

@       PTR     jdi.jdimedia.nl.
