Allow multiple address spaces when using ARM for virtual networks
When deploying services in IaaS using the Service Management API we have created a 3 tier virtual network in line with our on premise deployments - 10.125. 1x.x 10.25.x.x 172.25.x.x. If you try to add an additional address space when creating a network in ARM in the portal, you get a message saying you can't change the address space, which means you are limited to a single address space. Not the end of the world, but it means we are tied to classic until this becomes available.
Can we add multiple address space in Azure vnet?
