Go to any business with hardware that is 3-5 years old in its IT infrastructure and devices ranging from PCs running XP to the random consumer gear people bring in (cameras, printers, tablets, etc.) and see how easy it is to get everything talking on an IPv6-only (no IPv4 at all) network... including using IPv6 to do automatic updates and all the other pieces that need to work. We're nowhere near ready for that.
This is painfully true. I don¹t have much sympathy for Windows XP, since it¹s a year past extended End of Support, and it¹s a 15-year-old operating system, now five generations obsolete? But specific-purpose consumer electronics are failures: not just cameras, but game consoles, set-top boxes, audio-video systems. Even security critical stuff like software updates, anti-virus updates, CRL checks, are almost completely unavailable over IPv6. Unless you run a large enough enterprise to have your own update servers; then they can pull updates over IPv4, and serve clients over IPv6. However, if you dual-stack now, you¹ll be able to identify which things are still dependent on IPv4, and either engineer differently, or substitute equipment over time. Lee
