NetBox version

v4.5.2

Feature type

Data model extension

Proposed functionality

allow marking a range or oui of mac addresses to have uniqueness enforced so that there cant be duplicates of that mac address

Use case

to stop there being duplicates of mac addresses in specific oui's or ranges

we have an actual approved oui of mac addresses and we would like to keep them documented in netbox

however currently it is possible to create duplicate macs, which is understandable from a hyperv or proxmox pov where there can be duplicate macs across clusters. however for a certain oui's we would like to enforce uniqueness

related to #18040
