Re:How bad is IPv4 address exhaustion?

Could IPv4 address exhaustion be staved by opening some of the currently unused /8 blocks? For instance, Apple has the entire 17.0.0.0/8 block. If IPv4 addresses are really becoming scarce and demand is going up, seems like Apple could dole out /24 or /16 bit blocks to RIRs and make some money - which they obviously like to do. So why aren't they doing it? Maybe someone more familiar with the economics of IP has an idea.

There’s dozens of cases of this besides just Apple. Frustratingly, if you scan the legacy allocation /8 blocks (not done personally, but know someone who has), most of the ranges have no open ports on a majority of the range. So they literally are serving no justifiable (in my opinion) purpose.

I did IT support at a car dealership where some ancient line-of-business software needed a public IP for every Windows desktop it ran on to function properly.
No justifiable purpose, sure, but I can only imagine the tons and tons of legacy line-of-business crap out there with assumptions like this.
You nailed why I threw in the word justified intentionally. There’s plenty of reasons a public IP could be needed, but not justifiably (to me, your example perfectly illustrates that).
