That sounds more like they are excluding most corporate internal systems, (which would also happen to cover the systems run by government.)
If someone is paying you to write code, they have some say in the contract about how it is licensed. You could be upfront about only doing GPL, and they could be upfront about saying no. But if you try to do it after the fact, that’s a violation of the contract.
Sounds like sleep. Hibernate is when it turns completely off, such that you can leave it unplugged for a weekend and still have battery when it pops you back into your session. It takes longer to save and restore the session than sleep does.

Because bits are not expensive anymore, and if we used 64 bits, we might run out faster than the time needed to convert to a new standard. (After all, IPv4 is still around 26 years after IPv6 was drafted.) Also see the other notes about how networks get segmented in non-optimal ways. It’s a good thing to not have to worry about address space when designing your network.
