Though I do not agree that it will take so long time for first IPv6-only customers, RFC6540 just makes IPv6 mandatory ... it doesn't say IPv4 is. So to me IPv6 only is also Internet.

I rather see IPv4 exhaustion as another hurdle for any new player for the time coming. In practice it is impossible to start a new growing Internet access provider ... anywhere in the world. You'll need to start with some crippled IPv4 right away. As not all content is dual-stack, many MvdV>>> Do you know of any services that are only available via IPv6?

I did not fully understand the rules behind it. I'm not planning to understand it more deeply at the moment and I consider this kind of contest non-sense. ;) Greetings from Tartu, Estonia ...
