Nothing for World IPv6 Day

After months of anticipation, World IPv6 Day is nearly upon us.  Network equipment vendors, network service providers and networked enterprises have all diligently prepared and for twenty-four hours on June 8th we will all get to experience the fruits of that labor when more than three hundred websites offer their content using IPv6 in addition to IPv4.  If everyone has done their job right, what do we expect to happen?


That’s right.  The best outcome of World IPv6 Day would be a completely unchanged end-user experience, regardless of the fact that they now can use a new underlying network protocol.

Get Ready for Nothing

In order to best ensure that nothing happens, IT professionals should seek out latent IPv6 problems that may suddenly manifest themselves when so much IPv6 traffic appears.  What steps should you take to ensure that you experience nothing?

Until June 9th, the Cisco Technical Support Website will display a banner which tests the most common failure mode expected on World IPv6 Day.  Using some Javascript magic, the banner predicts the readiness of the host from which a visitor connects.  Ideally, the visitor will see teal text and a check mark icon indicating success, but a visitor who sees red text and an X icon may have a potential connectivity problem.

Even if the visitor can achieve the coveted check mark on that banner, it would not hurt to conduct a few more tests.

Remember:  World IPv6 Day starts at 0:00 UTC on 8 June 2011.  You can use to determine your local start time and local end time.

I hope that absolutely nothing happens.  Except for changing the foundation of the Internet, of course.

  1. Yes, that would be great. We expect some presenters at the NANOG meeting in June to present preliminary results. I don’t know of any formal, coordinated efforts to announce specific results, by I expect that individual participants will be sharing encapsulated information about their experiences.

  2. It would be really helpful if the participating websites shared some stats after the event. Stats such as their connectivity strategy on the server (dual stack?), bandwidth statistics (e.g bw increased by x%), cpu stats, memory, page load times etc…the type of information that will help engineers scope future migrations in non ipv6 organizations.
