NetBox version

v4.4.5

Feature type

Change to existing functionality

Proposed functionality

In netbox it's possible to create child range for prefix and to mark it as populated to prevent creating new addresses.

But in prefix's addres list ones from range are still marked as "available". When click to this "available", open menu of address creation but due to populated range, address is not created.

it would be better when if there is a populated range, addresses in it are not marked in list as available. For this case, first green available address has to be .21.

Use case

We not not automate creation of VMs and we do not use DHCP. Addresses are scanned from ARP tables. Users open prefixes to see for available IPs to manually assign to VM or server, but we need to have some addresses unused and we can't mark it visually explicitly.
