It's not too late to do something kinda like this using the ipv6 packet format, since routers already understand that. They'd put the whole "ipv4x" address space under a prefix.
- Dagger2 7mo agoWe already did it decades ago, with 6to4. The extra address space is under 2002:<v4 address>::/48.
- zadikian 7mo agov4-mapped v6 (rfc4038), not 6to4, right? It was only a transition feature and not how v6 was rolled out by default. I don't even have such an address. You enable v6 and it suddenly means you're reachable with the new addresses, typically assigned via slaac. Also idk if v4-mapped was meant to be split beyond /32s.
