No. It has to be a single-stack protocol fully backwards compatible. Dual-stacking is the fatal flaw. In the old days, the thinking was something like "oh everyone will dual-stack for 2 or 3 years, and then IPv4 will die". The problem is, we are 20 years into it already and possibly another 20 years going forward. Dual-stacking for 40 years is not a solution. Yes, it will take decades, especially since it is not even started. I have all the time in the world.
IPv4 will not be dead any time soon, this I think is clear to anyone dealing in network deployment,
I don't think it is to everyone. I don't know if you read Nanog, do you know what the latest idea an IPv6 crackhead came up with to accelerate deployment ? Taxing IPv4. A $2/mo/per IP tax, worldwide. https://mailman.nanog.org/pipermail/nanog/2019-October/103279.html https://mailman.nanog.org/pipermail/nanog/2019-October/103280.html I'm guessing that what comes next is a constitutional amendment to prohibit IPv4.
but again it (should) also be clear to these same people that to sustain and keep the anywhere-to-everywhere connectivity the IPv6 is the only viable option.
It's not even on the agenda. I don't have to be ready. I am quite happy in my dinosaur swamp with my dinosaur friends, my dinosaur supply chain, my dinosaur customers, and my dinosaur transit providers. My swamp is quite big, too. It's called the Internet. The asteroid that was supposed to extinct us came, 4 years ago in the ARIN region. Did not hit anybody I know. Did not even feel any heat or tremors. The extinction event did not happen. I don't need the anywhere-to-everywhere connectivity. As a matter of fact, if the Internet becomes balkanized and v4 and v6 split, I would not mind a bit. The IPv4 ecosystem is big enough to survive on its own for the next 30 years. There are plenty of dinosaurs left, and a lot of them have pretty big teeth. Who's next on my dinner menu ? Michel.
