Right, but the only way to prevent that being a problem is to not have the second half at all - either you have a manually allocated address, or you're not on the network.

Otherwise, we hit the same problem; you have devices that are dynamically assigned addresses, where downtime causes them to move, but the addresses are hardcoded in places you don't know about.
