It "died" as an Internet-Draft: https://datatracker.ietf.org/doc/html/draft-chimiak-enhanced-ipv4-03 https://datatracker.ietf.org/doc/html/draft-chimiak-enhanced...
- jandrese 4y agoI don't see how this has any advantage over just deploying more NAT like people are already doing. Plus it adds IP options which routers hate. They claim "EnIP supports end-to-end connectivity, a shortcoming of NAT, making it easier to implement mobile networks." but I don't see where mobile network operators would care about end-to-end connectivity?
