Alright DC hive mind, I seek your wisdom.

I know there are several IP Address Management tools out there that allow you to manage your networks by detecting active addresses, performing scans for inactive hosts, etc. What I am looking for is something different. I want to be able to assign a higher level subnet, say a /23, and break out by location where each network is allocated. I would like the ability to search for an active subnet, say a /27, to issue out to a new device or mark a range no longer in use and available for issue.

Does such a product exist?

"State of the mouser" :-D
