> An actor can be in one of several states: You rigged the list of states. There is more than one possible state that include IPv6 connected as the baseline. For instance, IPv6 connected with access to 6/4 web proxy and 6/4 smtp forwarder. There are other possibilities. Consider a large community of users (community meaning they communicate a lot with each other) who have such an IPv6 service. They can freely use IPv6 supporting applications with no NAT worries. Access to the v4 Internet is restricted but no more so than in the average v4 corporate network. Now what if that large community of users is a country where people do not speak one of the world's top ten languages. The game is too complex for game theory to analyze since it is too hard to get the right list of states. > Rather than fight the dynamics of a market with a billion > participants I believe that we should embrace them and > remember that taking IPv4 to end of life is not exactly an > unacceptable outcome. The key is to channel people into > IPv4-NAT/IPv6 rather than IPv4-NAT. I would be slightly less specific and say that we should channel people into IPv6-gateway-IPv4, meaning that they get IPv6 connectivity but some sort of gateway support services to access IPv4 hosts. Those gateway support services will probably be a whole smorgasbord of things including Teredo and simple dual-stack proxy servers. Perhaps the pioneers will be those ISPs who currently offer some sort of managed/restricted service such as Family Safe Internet or Christian Net. It doesn't matter who takes the first steps. Once the technical principle is shown to be workable and profitable, others will adopt it. > The way that I would go about this is to introduce a gold > standard for next generation gateways that provide other > features that the consumer is likely to consider desirable. > Like being maintenance free, working without the complaints > and setup time that current devices require. I agree that those are desirable goals for the gateway standard. --Michael Dillon _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
