Can I combine assignments? How?

If you make a new assignment for the same organization with the same netname, it is permisible to combine the objects.

You can create one new object for the whole range, and delete the original object(s) for the smaller range(s). Please note that if you received approvals from the RIPE NCC for your assignments, the netname in the database needs to match EXACTLY the netnames that were approved, and the first changed line date must be on or later than the most current approval date. If one or more of the netnames are changed, or if you are unsure, please contact hostmaster _at_ ripe _dot_ net.
