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.
