Remember the World IPv6 day ? In 2014 a few of us (about a hundred of folks around the world at the moment) are going to do a "World IPv6 only day" (turn off IPv4) on the 06/06/2014, for ourselves. If we can't work successfully during this day using IPv6 only - then we'll take a day off (Conveniently, it's Friday). If you are someone doing computer networking professionally - why not join us ? We're tracking the count of those who will turn the legacy IP off for a day via an Avaaz "petition to all the computer professionals". http://preview.tinyurl.com/noipv4 http://preview.tinyurl.com/noipv4

But we won't be able to browse Hacker News! (Even though they use Cloudflare now and could just turn on the AAAA records).

  Yeah maybe if we all ask pg nicely, he will do it ? :) As a backup plan - cloud-based NAT64 is a fair game for the day, search "go6 nat64".

    I never tried nat64. If github got their shit together and installed ipv6 I would be very happy...

      In github case since it's server side only and FOSS, they could probably go even further and go v6only and do stateless translation for ipv4 clients. But that's a bit too hardcore :-)

        I don;t mind so long as I can stop running NAT so my test VMs can pull from github when everything else they do runs over v6... (actually buildbot doesn't work over v6 only either).

  So in other words productivity might skyrocket for the participants.

We moved our whole headquarter on dual stack a while ago, and periodically I'm turning off IPv4 on my laptop to check what the "user experience" would be with IPv6-only... ...well, 9 URLs out of 10 are unreachable. It would be impossible to use for any user.

  Try with nat64. Not entirely clean experiment, I know (IPv4 upstream of translator). But the result is quite usable. Ping me via mail if I can help with the setup, we did this setup several times with reasonable success.

    Thanks, but that's exactly what I wanted to avoid. With my little unscientific "experiment" I wanted to get a practical taste of how big the IPv6 Internet is right now... "really small" would be the answer :)

      Depends on what you do. YouTube should work fine, netflix does as well. That more than 50% of traffic for some. The long tail is indeed long :-) There with no transition tech you get about 4.8% [1] I think there are two strategies: 1) keep your network as dualstack until the above %% is sufficiently big (how big ?) and then just turn off ipv4 and if something is not available, "too bad". 2) add the band-aid to go ipv6->ipv4 (nat64) and turn ipv4 off in the network as soon as the above %% is sufficiently big (how big?) The additional factors are presence of NAT44, OS mix, network management, etc... Too early for both now, but I am betting (2) will happen earlier. What do you think ?

        Netflix kind of works, but the geolocation is borked, so I had to turn it off (it thought I was in US and then denied access).
