Hi,

In my company, I have multiple separate sub-systems which have the same prefixes/addresses/vlans/VRFs.
ex :
system-A_prefix-A(192.168.1.0/24)_server-A_192.168.1.1/24 (vlan=VRF=admin),
system-B_prefix-A(192.168.1.0/24)_server-A_192.168.1.1/24(vlan=VRF=admin)

When I try to put that into IPAM section, I can add the same prefix two times (192.168.1.0/24), but there is logically a duplicate prefixe and if i had a sub prefixes like 192.168.1.0/25, this last has more than one parent.

How can I add multiple systems in netbox with the same prefixes/addresses/VRF/VLAN ?

Thanks you for your help :)
