Reverse lookups only work in my net

[Marc Eggenberger]

Hi there.

We have several C-classes and I did the reverse-lookup for some of then 
(mainly the dial-in range).

Reverse lookups work fine If I have my nameservers to look up ... If I 
do a reverse outside my network it won't work.
The IP Ranges are ours (registred at RIPE) but I seems that I am missing 
something ... what do I have to do that outside nameservers know where 
to ask for reverse?
