There are a few reasons we might not want to see a subnet in the Summary, and prevent them from consuming slots in the top xx Space Used:
- The net is small - /30, yet we want to track the address.
- The net is manually maintained - not DHCP
- We purposely want DHCP to limit the number of addresses, and don't care if we run out
Ultimately, it would be best to be able to set the alerting levels on a subnet basis, with a report that shows the alert levels.
