>My point is that if you are not connected to the public internet at all I don't see why you should be expected to follow the rules of the public internet (who owns what). You can use whatever rules you want for your own private network. Hypothetically if you were dealing with a network that had zero access to the outside world then you are right, it doesn't matter. You can use whatever IPs you want and it wouldn't make a difference. Its a bit of a moot point though since outside of niche situations like high security air gapped networks you don't really see that scenario anymore. Yes, the network at a nuclear missile silo could do that but everyone else is connected to the internet.
