Indeed, but its something extra that _you_ have think about after you've setup your VPC (if youre on AWS) not only does it mean you can deploy/configure un routable IPs by accident, its using a mechanism that _slows down_ your VPC, and adds a minefield of confinguration errors. its just madness.

It's just a LAN, why would you ever statically assign IPs? especally at scale, especially if you have a dynamic ever changing workload. Deploy a pod, two network interfaces, macvlan & AWS does the rest. Put a cloudwatch alert for DHCP exhaustion, or put a resource limit in for each AZ.

Put it this way: Why do you want to have to think about subnets _after_ you've created your VPC? (unless you've reached a limit...)
