I just read something about IPv8! Can anyone confirm this is real?
Lots of people have come up with alternate L3 protocols for the Internet. For example, check out [1] which goes up to 999.999.999.999.999, or [2] which gets updated with some typo fixes every 6 months each time it's about to expire.
Someone did post another one of these recently, but it's just a random person on the Internet. The IETF's draft database is more or less a pastebin service -- anyone can upload something there without it being a thing that's being taken seriously.
Sometimes you get drafts like [3] as a demonstration of that.
