Hello!
I have an OnPrem subnet of 10.23.0.0/16 that I was given to use for Azure subscriptions. As of now I need to have 10 subscriptions and each subscription will have (2) VNETs that will connect back to OnPrem via VPN or Express route.
Each VNET will have its own subnet; 10.23.x.0/24. Im curious if I could create each subscriptions VNET with the same OnPrem of 10.23.0.0/16 and break it down via subnet; 10.23.x.0/24?
Will there be any conflicts between VNETs and Subscriptions by doing this method? It is safer to create each subscriptions VNET as 10.23.x.0/24 and break it down with subnets beneath that?
