The US Federal Government, like many large IT organizations and other national governments recognizes the important of transition their networks to support IPv6. On Sept 2010 a memo on the transition to IPv6, was issued by then Federal CIO; Vivek Kundra, outlining the government’s commitment and rational behind expediting the operational deployment and use of IPv6.
Cisco.com users on World IPv6 Day 5 to 10 times more likely to use IPv6 than visitors to other websites
While looking over our data from World IPv6 Day, we found that 2.26% of all users who logged in with a username and password to www.cisco.com on June 8 did so over IPv6. That is nearly an order of magnitude greater than between the less than .2% and .3% averages reported by sites operated by more broadly visited websites such as Yahoo, Facebook, and Google. In contrast to those who logged in with their username and password, the total proportion of unique users who visited our site via IPv6 was estimated at just under 1.5%, which still represents at least a five times greater likelihood that a given cisco.com visitor reached us via IPv6 vs. the broader population of Internet users.
This shouldn’t be surprising at all. The cisco.com user base is made up of networking and IT professionals that are likely more willing to go out of their way to obtain IPv6 connectivity than most users. We hope that you will continue to use IPv6, show others how, and that we’ll have even more IPv6 users the next time we make www.cisco.com AAAA records available (see Fred Baker’s blog on what might be next).
In terms of overall traffic, our netflow statistics reported that 1.11% of traffic to and from www.cisco.com was served over IPv6. This traffic was delivered via an IPv6 to IPv4 load-balancing proxy function within our Application Control Engine (ACE) 30, allowing us to keep our existing production www.cisco.com virtually untouched while still providing an IPv6 web presence. On June 8, we used a pre-release version of code, alongside other Early Field Trial (EFT) customers. Matthew Laslie, Network Engineer and Architect at Savvis writes:
“Savvis was looking to provide IPv6 reachability to our primary websites without performing major modifications to our backend application/security infrastructure. After evaluating several solutions, Savvis selected the Cisco ACE. In the span of two short days the ACE was fully installed, configured and providing IPv6 reachability for several Savvis corporate websites.”
In addition to the participants that officially signed up for World IPv6 Day, others moved ahead on June 8 without the formalities. Cisco EU IPv6 Deployment Council member and customer Strato let us know after World IPv6 Day that they are now announcing IPv6 AAAA records for over four million domain names. Wilhelm Boeddinghaus, Head of Networks at Strato writes:
“Our customers don’t ask us for IPv6, nor do they ask us for IPv4, they ask us for the Internet, and that’s what we give them. Today the Internet is more than IPv4. The working Internet provides both protocols.”
Those four million domain names represent the ability of the content side of the IPv6 Internet to move very rapidly to IPv6. The fact that they decided to leave IPv6 on after June 8 is testimony to the confidence they have in IPv6, and that it is the right thing for their customers. There were a number of other websites that opted to keep their AAAA IPv6 records active after the 24 hour test on June 8, including our own www.scansafe.com, which moved to IPv6 by announcing AAAA records on World IPv6 Day and continues to today.
Given the relatively high turnout of IPv6-enabled www.cisco.com users vs. the rest of the industry, we have yet another clear data point of the importance of IPv6 to our customers. With all the success around World IPv6 Day, it seems hard to fathom that this will be the only event of its kind and we are eagerly looking forward to participating in and helping our customers with the next “World IPv6″ event. Stay tuned…
Back In January, Cisco was among the very first to respond to the World IPv6 Day rallying cry launched by the Internet Society and major Internet content providers such as Google, Facebook, Yahoo and Akamai. Since then, we have been working across the industry with other participants, customers, and users to ensure that this global experiment was a success.
At midnight UTC on June 8 (5pm at Cisco Headquarters in California), www.cisco.com alongside hundreds of other World IPv6 Day participants announced reachability to IPv6 in the global Domain Name System. Millions of lines of code and countless man-hours of work over the past decade developing the various bits and pieces of IPv6 in network equipment and software across the globe were exercised in concert like never before. As we watched the various test sites and dashboards move to “green” status for IPv6, sighs of relief were heard followed by a sense of great satisfaction among everyone involved. 24 hours later, no major issues have been reported.
All in all, World IPv6 Day seems to have gone off without a hitch.
IPv6 is the only long-term solution the industry has available to continue Internet growth in the manner that the world has come to expect. We believe that this day will be looked back upon as a watershed moment in the global deployment of IPv6 -- we have verified not only that IPv6 works on a global scale, but also that it can work alongside IPv4 until the day that we can all begin to turn IPv4 off.
Cisco has been involved in developing standards and products for IPv6 since its inception, and by being part of World IPv6 Day from the very start we have learned a great deal in how the various implementations over IPv6 operate with one another. We will be reporting more on our findings in the coming weeks -- for now, it’s been an exciting 24 hours, and all those that helped get us here are going to get some much-needed rest.
