> The long tail doesn't matter. We’re talking about the logistics of a bet, it’s the only thing that matters in this context. The big transit providers pay very little to carry ipv4 prefixes. They will never even consider cutting it as long as there are any semi large content providers offering v4. Transit cores are prefix-free with segment routing so the cost is basically just the device that peers at the exchanges with other peers. > The appropriate comparison is leaded gasoline. It is not. The price dynamics make it so cheap to keep supporting ipv4 that it’s nothing like the unleaded switch. That’s before you even consider how dumb “banning the sale of new IPv4 devices” is.
