T-Minus Zero and Liftoff! World IPv6 Launch Has Begun.

June 5, 2012 - 5 Comments

The launch of the world’s new Internet Protocol, IPv6, has started. With official participation of over  3000 website operators, 50 network operators, and multiple home networking vendors, this is the largest concerted effort to move the industry towards IPv6 ever. Building upon the success of last year’s test run on World IPv6 Day, the Internet Society, with strong support from industry leaders, decided last January not merely to test IPv6 again, but to turn it on and leave it on.

As with a rocket launch into space, this is a moment where the herculean efforts of individuals from across the globe have converged to set off a chain reaction of events towards a common goal. The goal in our case is nothing less than retrofitting one of the largest operational systems mankind has ever created with a new foundation to help propel the Internet to the stratospheric levels of growth and innovation the world has come to expect.

Cisco has been preparing for some time and is proud to be among the founding participants of the World IPv6 Launch. Cisco has now permanently enabled IPv6 on www.cisco.com  and has IPv6 enabled by default throughout our line of Linksys E-series home routers. We are rolling out IPv6 progressively across our own enterprise network, are leading the way in IPv6 Certifications, and our solutions for IPv6 deployment are in use by service provider and enterprise network operators across the globe. Most importantly, we will be continuing to work closely with our customers, Cisco Services, and development teams to ensure that any problems that may arise are addressed as quickly and efficiently as possible during this critical phase of deployment.

This is a giant leap forward for the Internet, but there is still much work to do in order to release our dependence on IPv4 and allow IPv6 to reach its full potential. While we now have websites representing a majority of Internet traffic advertising their IPv6 reachability to the entire world, the majority of new Internet connected devices shipping with IPv6 built-in, and more Internet Service Providers than ever before enabling IPv6 for their customers as part of normal business, we will have to fly with both protocols at the same time for several years before we get to the point where we can cut loose our first-stage IPv4 engines and soar to new heights without them weighing us down. We have certainly left the platform now though, and are on a clear trajectory toward significant and sustained growth of the Internet based on its widespread adoption of IPv6.

Congratulations to everyone who helped to make this historic launch happen. Because of your vision, dedication, and hard work, IPv6 has left the laboratory and entered the mainstream. The world has its new Internet Protocol.

  1. I am waiting for the day when my drawer will know that I am running out of clean socks and communicate with my laundery service. The laundermat computer will dispatch a google car to my apt where my doorman will put my dirt laundry in the back, and take it back to the laundromat.
    Hope IPv6 can help me maintain an ample supply of clean socks.

  2. My First Computer was a Radio Shack Floppy (and I mean Real Floppy Disk Type)
    A dos System.
    To access the internet I had to dial the Phone and put the receiver in a socket cup while on the internet. I think the main access on the internet was CompuServe.
    Computer Cost in those days was $3,600.00 without matrix printer.

    The Internet has come a Long Way in a Short period of time
    I am so excited that this new system ipV6 is being activated to help the future of our children.

    I install CCTV equipment and I use Linksys Cisco Routers

    Thank You, Ken

  3. we are entering in the new world of addressing of electronics devices

  4. Indeed congratulations to everyone at Cisco and other organizations for the hard work done up to and until this day.

    What is important to remember though is that I think yes, this is a big step, but it is now it begins.

    When a certain threshold of organizations use IPv6 [which might happen today], it is important to be able to build carrier grade IPv6 networks, and not the sort-of-experimental that has been the case so far. I have as late as last week seen terrible problems with uptime on IPv6 access to regulators websites in the world while IPv4 “of course” is up and running.

    So, this is not the end. This is not the beginning of the end. This is the end of the beginning.
