I'm trying to document the folloging:
I have a /24 Subnet, which is split variably into many /30 or /29 Subnets. So I created this prefix structure:
10.202.0.0/24
10.202.0.0/30
10.202.0.4/30
10.202.0.8/30
...
All prefixes have the "Is a pool" setting turned off
When I check the Child Prefixes Tab of the Prefix 10.202.0.0/24 it lists the utilization perfectly fine. However, when I want to get an overview of all the Used or available IP Adresses, I see all the netowork and broadcast IPs as available. Even more so, I can create an IP Address 10.202.0.3/30 which is actually a broadcast address and therefore not usable.
This was already reported as an issue here: #13523
but unfortunately according to the resolution, this is expected behaviour and there are many scenarios where this is useful and necessary.
I have two scenarios where this is actually not the case and I'm wondering if this could be implemented as an optional feature?
There is after all the option in the prefex to treat it as a pool (where net and brodacast addresses are usable) but it seems that this is not taken into account for child-prefixes
For one scenario I'm using the concept of routed access. That means there are two big L3-Switches witch connect to lots of Access Switches using small /30 networks (Each of the big L3 Switches get one /24 subnet, which is split into multiple /30 subnets)
The other scenario is where even the endhosts are connected to the switch using small /30 networks, so there is no L2 at all. That kind of setup is used in a SMPTE-2110 media fabric.
In both scenarios I'd like to get an overview of free ip addresses by looking at the /24 subnet rather then clicking into every single /30 subnet.

I'm running netbox 4.2.2
Thanks a lot
