Hi all,

I am not sure if this issue is already discussed.

Example:
Prefix 10.0.0.0/24 - type container
child prefix 10.0.0.80/29 - all 6 usable ip's are reserved. Prefix utilization is 100%

If I am in the child prefix view, all ip addresses are used and there is no add ip address button. If I go to the parent prefix view and try to add 10.0.0.80 or 10.0.0.87, there is no error. After that the child prefix utilization is shown as 116%.

Netbox version: 2.4.6
