NetBox version

v3.4.4

Feature type

New functionality

Proposed functionality

When managing infrastructure for multiple customers (tenants) we would like to allow registration of private IP-ranges for those clients. Obviously these aggregates (like 10.0.0.0/8) will overlap.

The new functionality should allow agregates to overlap when different RIR and Tenant are selected.

Use case

NexBox users managing infrastructure for multiple customers that have overlapping ip-aggregates.

Database changes

allow ip aggregates to overlap when different RIR / Tenant (group) is assigned to the aggregate.
maybe add 'are you sure' checkbox

Thanks for your contribution.

Are VRFs not working for this purpose in your use-case? I understand that they do not apply to aggregates, but technically, there is one and only RFC1918 172.16.0.0/12 aggregate that exists, for instance.
