As long as they only speak ASCII, yes. > Now imagine two endpoints talking a not backward compatible pair: A only speaks IPv4, and B only speaks IPv6. Will they be able to communicate, at least something? That's why you deploy IPv6 dual-stacked with IPv4. That way, if two parties only speak IPv4, it's completely backwards compatible. > See the difference? Sure do I see the difference. What I don't see is how to apply any of that to the v4 to v6 transition in a way that would have any advantage over how it is being done now.
