> Who owns all these new addresses? You do. If you own an IPv4 address, you automatically own the entire 96‑bit subspace beneath it. Every IPv4 address becomes the root of a vast extended address tree. It has to work this way because any router that doesn’t understand IPv4x will still route purely on the old 32‑bit address. There’s no point assigning part of your subspace to someone else — their packets will still land on your router whether you like it or not.
So the folks that just happen to get in early on the IPv4 address land rush (US, Western world) now also get to grab all this new address space?
What about any new players? This particular aspect idea seems to reward incumbents. Unlike IPv6, where new players (and countries and continents) that weren't online early get a chance to get equal footing in the expanded address space.
