A Swiss VM hosting provider has a technical blog post about how to kill IPv4 completely on FreeBSD. That is to say, turning it completely off, not just preferring IPv6. They then solicit concrete solutions describing, along with a proof of concept, how to turn IPv4 completely off in other operating systems and allowing them to communicate with IPv6 only.

    MAC addresses have not been guaranteed unique since Linux let you set them.

    I remember Ethernet cards in the early '90s that let you set MAC address in the driver. Even if it was set in hardware there are people who can spoof it.

    ARP protocol will be unhappy if you set every ethernet card on your lan to 1:2:3:4:5:6, so in the sense that they're unique on a link-local lan that actually works remains correct.
