What about home private network (for smart home, for example)?
Nothing stops you getting a subnet allocated from your local RIR and announcing that on the internet, if you care about that sort of thing for your home network though. You just need a decent ISP.
I’ll just leave that there.
No, I can’t just choose to have a decent ISP. I live in the real world where there’s only one choice where I live, same as a rather large majority of people in the world.
