Deployment Type

NetBox Cloud

NetBox Version

v4.3.1

Python Version

3.10

Steps to Reproduce

  1. Create IP prefix (for example 12.12.13.0/24)
  2. Check the "Available IPs" for IP prefix
  3. Create IP range (start 12.12.13.1/24 end 12.12.13.50/24) and mark it as utilized
  4. Check the "Available IPs" for IP prefix and you will notice that no change in the number of "Available IPs"

Expected Behavior

When IP range created and marked as utilized, the available IPs in IP Prefix should be decreased with the same number of host IP range in IP Range

Observed Behavior

notice that no change in the number of "Available IPs" for IP Prefix after creating IP Range

This is actually by design, if you look at mark utilized on IP Range it states "Affects utilization calculation without restricting new IPs" You can set mark populated to remove it from the Available IPs.
