It's not even the first IPv8. There was an IPv8 doing the rounds in the late 1990's for a while. I had some trouble finding references, but I think this is the sanitized version: https://tools.ietf.org/html/draft-terrell-ip-spec-ipv7-ipv8-... I have fond memories of reading about how stargates, galaxy routers etc, etc were going to solve all our problems. The IPv8 in the link is a far more pedestrian read.
