Then there's a veritable black hole of various crappy security cameras, IP phones, and WiFi printers. And they can live for a veeeeery long time.
And I don't think I've ever seen a hotel network with IPv6 support. And I've actually seen a hotel (in Palo Alto) that gives out real IPv4 addresses to clients.
Also, it is eight years in the future. What future devices won't support IPv6?
This is also about the Czech government sites removing IPv4 support. What devices that would be used to access site won't support IPv6? They all do today.
As an aside, I notice a lot of the recent commits to the ESP32 repo are for ipv6 fixes. It already works in the tasmota esp32 builds on devices at my place.
This said, by then, maybe the core OS will not be metal, but Linux on all these device and we'll get top ipv6 support.
More likely, in 2032, well have a bunch of crap, built from very old SOCs running Linux 2.4.
Nobody's sunsetting IPv4. It will fade into obscurity on its own as IPv6 adoption increases and IPv4 addresses become increasingly hard to get, as it should.
IPv4 will be around for a long time. Nobody will care if it is running on internal network. Or quadruple NATed. There are enough IPv4 addresses for sites to have them. But not enough for every user.
Sounds like IPv6-as-botnet-DDoS-prevention is a viable strategy! Can't get DDoS'd by the unmaintained crap if said crap doesn't even speak the required protocol!
