In recent interviews about World IPv6 Launch I’ve been asked by several different people whether or not I think there needs to be some kind of a “Flag Day” on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6).
I don’t think a flag day is needed. World IPv6 Launch is just the right thing.
It’s worth looking at some previous flag-type days to get a better sense of why.
