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.

    Not France, but also EU. NATted networks with hundreds of customers are ultra-popular here as the opinion about Internet is that it's Google and FB. Yes, the Internet :(.
    There is a nice question for a network test: How many NAT routers are between you and the world? I traced my network and there are 5. One is mine, so I can configure it as I want. One is from my provider. Third one is from provider of my provider, fourth and fifth are in computational center being the proper "provider" of Internet. Summing up: 5 NATs to pinch a hole in.
    When I wanted to get a single-port pass-through (my computation machine returned its state... by periodically throwing strings through netcat, I'm lazy) I had to go to 3 people and the hole disappeared a few months later when computational center upgraded their routers.

    The problem is that you may get a really poor telecommunication-grade Internet (fortunately not a famous 9600/8/n/1, but it started this way), with world IP but expensive and really slow, or faster and cheaper one without IP.
