alt Hacker NewsSounds like this is exactly that. Too bad they didn't do that first, and we've had a couple decades of failing to widely adopt IPv6 because it's too complicated and confusing.
"1.7. Backward Compatibility and Transition
IPv4 is a proper subset of IPv8:
IPv8 address with r.r.r.r = 0.0.0.0 = IPv4 address Processed by standard IPv4 rules No modification to IPv4 device required No modification to IPv4 application required No modification to IPv4 internal network required
IPv8 does not require dual-stack operation. There is no flag day. 8to4 tunnelling enables IPv8 islands separated by IPv4- only transit networks to communicate immediately. CF naturally incentivises IPv4 transit ASNs to upgrade by measuring higher latency on 8to4 paths -- an automatic economic signal without any mandate."

How can we adopt this 30 years back!?
IPv6 doesn't require modifications to IPv4 devices, applications, networks etc etc either. You just cannot reach IPv6 networks and devices from them, and the same applies to IPv8. 8to4 is nothing innovative because 6to4 already exists. In the end this proposal has all the disadvantages of IPv6 with less advantages.
