Well, we have 12 millions+ nodes happily communicating every day via IPv6 that suggests IPv6 is a pretty successful "experiment."
I know you meant to say, "Failed experiment for consumer web connectivity" - but, I think it's important to remember that IPv6 has some very successful niches. Mesh networks, Smart Grids, anything with large scale flexible address and routing requirements has been using IPv6 very successfully for at least 5+ years now.
The only real competition IPv6 has over the next 20 years for global routing dominance though, is, ironically, IPv4.
The main reason is that all the Autonomous Systems have to have some common language to communicate, and share routing updates, and, for better or worse, IP is the "English" of network engineers when it comes to internetwork routing.
- tptacek 13y agoI agree: IPv4 is going to be a fierce competitor for the slot that IPv4 currently occupies and IPv6 hopes to occupy. The point of an overlay design is to moot the point of which one wins, by "pushing them down" the stack and building something new on top of them. Frame Relay is a good example of what this design looks like: a "layer 2" technology with "layer 3" features (Frame had aspirations to be a layer 3 technology) that only network operators care about, because no Frame user ever expected global all-points connectivity to be provided by Frame. IPvX should be demoted to Frame Relay status: a very flexible way of providing point-to-point connectivity between nodes that will provide global connectivity through routing done at a higher layer.
