10.6 Protection of Address Space

The inetnum and inet6num objects represent address space allocations and assignments. The "mnt-lower:" attribute is used to reference a mntner object that authorises the creation of more specific inetnum or inet6num objects. If no "mnt-lower:" attribute is present, one of the "mnt-by:" attributes of the parent object will be used instead.

This parent authorisation is only required when an inetnum or inet6num object is created. This authorisation is in addition to the authorisation of the individual object itself.
