Type: regulative
Decision
VNet address spaces must be allocated by querying live Azure, not by reading an assignment registry.
Why
Without querying live state, address allocations drift and VNets cannot peer.
Violations
- VNet with a manually assigned address space.
- Allocation recorded in a registry file and trusted without a live check.
