What will break on IPv6 day?

  • 772

As you are probably aware World IPv6 day is coming on 8 June. Our network is IPv6 enabled, so the basics are all there, but our users currently defaults to IPv4 for almost everything (IPv6 is <1% of the external traffic). I have verified that our DNS servers handles IPv6 properly, but I am not certain what to expect when the users start to get AAAA records for services like Google and Akamai.

    My guess is nothing or very, very little. The link you posted says that those organizations will offer their content over IPv6, it does not say that they won't continue to offer their content over IPv4.

    Probaly 99.9% of the worldwide network structure is not ready to move exclusvely to IPv6. Do you believe that those content providers would purposefully cut off 99.9% of their user base for a full 24 hours... as a test?

  2. As Joe said. If you read their FAQ on their site, they answer this:

    How will World IPv6 Day impact Internet users?

    One of the goals of World IPv6 Day is to expose potential issues under controlled conditions and address them as soon as possible. The vast majority of users should be able to access services as usual, but in rare cases, misconfigured or misbehaving network equipment, particularly in home networks, may impair access to participating websites during the trial. Current estimates are that 0.05% of users may experience such problems, but participating organizations will be working together with operating system manufacturers, home router vendors and ISPs to minimize the number of users affected. Participants will also be working together to provide tools to detect problems and offer suggested fixes in advance of the trial."
