alt Hacker NewsOur world. It was a good design in our world.
I don't think v6 is the absolute pinnacle of protocol design, but whenever anybody says it's bad and tries to come up with a better alternative, they end up coming up with something equivalent to IPv6. If people consistently can't do better than v6, then I'd say v6 is probably pretty decent.
In retrospect I think just adding another 16 or 32 bits to V4 would have been fine, but I don’t disagree with you. V6 is fine and it works great.
All the complaints I hear are pretty much all ignorance except one: long addresses. That is a genuine inconvenience and the encoding is kind of crap. Fixing the human readable address encoding would help.
