      That forces the DNS resolution itself to only go over IPv6. I think what you want is host -t AAAA slashdot.org.

      No, it says you're good for connecting to sites that are IPv6 enabled, not that you're good for connecting via IPv6.

      A lot of people are concerned that shoddy configuration by ISPs will mean that sites advertising on IPv6 *and* IPv4 will be unreachable by people trying to connect over IPv4.

      Safari, for example, had a bug until recently that caused page loads to fail if the site has an IPv6 address but the client doesn't have connectivity. In addition, there are a bunch of autoconfigured tunnel technologies that can cause problems. See, for example, APNIC's chief scientist's report on Teredo: http://www.potaroo.net/ispcol/2011-04/teredo.html

      Yes. And when that stage is reached, we can start turning off the IPv4 stuff, because there's no benefit to it.

      Because if the client and server both have IPv6 connectivity, many clients will connect by IPv6. As they should. The problem is that just because both have connectivity doesn't mean they have connectivity to each other - the IPv6 part of the internet is still being configured, by admins largely unfamiliar with the new technology and on hardware with had support added as an afterthought. It'll get better, but right now there are still many links that have problems. The IPv4 side has a few too, but it's had a decade for engineers to fix almost all of them.

    6. Re:Where is the Google test? by petermgreen · · Score: 3, Informative

      Most clients will fall back to v4 if v6 fails. The problem comes when the v6 connection attempt gets no reply at all (e.g. due to routing problems, firewalls, links that are down but the system doesn't know they are down or some combination), the client will then wait for it to time out before falling back which if the client uses standard OS timeouts can take an excruciatingly long time.

      The cause of the packets not getting any reply at all may be local to the client but it could also quite possiblly be in an ISP nework somewhere. Remember the internet (whether v4 or v6) is just a (very large) set of network providers cooperating (through ICANN and the organisations it delegates to) to use non-conflicting addressing and to foward traffic to each other. Even on the better maintained v4 side it's not that unusual for two ISPs to be unable to exchange traffic for a while due to some screwup.

    That's because you're querying for A records and not AAAA.

    World IPv6 day is unfortunately DOA due to Cogent being a bunch of jackasses and not allowing certain peering arrangements. There are unfortunately two IPv6 Internets. One of people who use Cogent and one for everyone else.

    Google, Yahoo! and Hurricane Electric, as well as many other sites are all on Cogent's "no peer with you" list. If you're a Cogent customer you should get on the phone.

    1. Re:Cogent is ruining it by Agent+Green · · Score: 4, Interesting

      I think it's a matter of Cogent trying to strongarm its position. It wouldn't be the first time Cogent has done this and it certainly won't be the last. Doing a Google search for "peering dispute", and not including Comcast (to exclude the Comcast vs. Level3 dispute since it's newer and ongoing), almost every old entry involves Cogent duking it out with someone. They win customers on price, but things seem to be lopsided enough that they get into a scuffle with a number of the other Tier-1 providers.

    The test is aimed squarely at you.

    What stops the large content providers from serving over IPv6 right now today is a level of brokenness that affects a fraction of a percent of users. These are computers or networks which are nominally IPv4 only, but have some misconfigured IPv6 setup that is actively causing problems connecting to sites. The proportion of users is tiny, but if you're facebook, that's still a lot of users. Wednesday next will expose these problems on a temporary, scheduled basis.

    If you run IT support for an organisation, it would be wise to see the results of, say, the RIPE IPv6 eye chart on your client machines.
