IPAM: Do unused IP addresses could toward your license allocation?

Jump to solution

Suppose you had a 16,000 address license and were adding a class B address space (65,535 address) - would IPAM only be able to scan the first 16,000 of those addresses for used/available status? Thank you for clarifying.

No, only IP addresses found and allocated count towards license. 

So in your example: 10 addresses found - 10 licenses used

Can scan any amount of space, but once you hit your license cap of found addresses it stops storing the results for anything else. I don't know off hand if it actually stops scanning or just stops saving the results, but the effect is basically the same for us.

But to clarify - if you have a 16000 IP license and you try to scan 20000 and only 10 addresses are actually reachable, you're saying the process stops once those first 16000 have been scanned. Is that correct?

To clarify further, any IP address that is not available will count towards the license.

If you scan 20000 IPs:

  • 1000 come back as used
  • 50 are reserved  (excluding network/broadcast addresses)
  • 10 are transient (were used but didn't respond in latest scan)

Then you will have 1060 addresses used on your license.
