I think the problem is that we don't know how to do 'proper' address selection. It would be nice if 5 or 10 years ago there would have been a good standard to do address selection. Today, we are just in the stage of doing more experiments. There is one thing that works well. And that is, you only assign global IPv6 addresses to a host if global IPv6 connectivity is at least as good as IPv4 connectivity. We want large scale deployment of IPv6 today not some time in the future when we finally figured out address selection. And that means that today we have to make sure that users don't end up with unreliable IPv6 connections. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
