Inetnum Object

Hi,
 I have some problem to make new registration at RIPE NCC DB from some
 allocated range  because in the DB there is not
 its related inetnum object (for i.e 151.39.0.0/16). I know that this object
is created by the
RIPE at the first assignment, but I will already use this range because it
was allocated to us by the ARIN in the past and we had made some assignment
 for our dial-up users without problem with the old Ripe-181 format.

Now when we try to make a new registration we receive the following

Can you tell me what I can do?
