Cisco Live US landed back in San Diego this year and (together with 25,000 others) I packed my bags for a week of technology dialogue and professional excitement. Here is my personal summary of (what is always) one of my favourite weeks of the year.
As we entered the event, IPv6 deployment in the US was sitting at around 18% with the ARIN IPv4 free pool on the brink of total depletion.
Once again this year I was lucky enough to be closely involved in the event: as IPv6 Session Group Manager (together with my colleague Eric Vyncke) we are jointly responsible for reviewing all IPv6 content. Within Cisco Live, IPv6 has risen to a position where we are now reviewing and instilling content in almost every single Breakout and Techtorial that includes IP as a component part. This year our specific reviews touched:
- 30 Technical Breakouts
- 3 Techtorials
- 4 Hands-on Labs
There were many other sessions that made reference to IPv6 but these were the specific sessions Eric and I reviewed.
We also directly insert into the program, and this year we positioned 3 specific IPv6 sessions:
Here you see the audience listening to “Addressing Networking challenges with latest Innovations in IPv6 – BRKRST-2616” (one of the last sessions offered in San Diego):
This session created a particular “buzz” for a number of reasons:
Mark Townsley did a fantastic job of wrapping up all of the work we have been doing in IPv6-Centric networking since announcing the effort to the world just over a year ago. This was also formally the “debut” of IPv6-Centric at Cisco Live (expect more in future). Follow along via:
The IPv6 Technical Breakouts reached a total audience of over 2500 attendees. Looking at the surveys, it seems everyone was very happy with the education delivered.
The audience feedback on these sessions was really nice to read:
- A lot of very valuable info
- Good info. Well presented.
- Great content and great speaker.
- Interesting and very well explain
- Interesting developments coming in IPv6 with some slick solutions.
- This was the best session in Cisco Live 2015.
- Great idea having audience to do an address exercise
- Liked the exercise at the end. Good content and explanation of things to avoid.
- Loved the exercise
My congratulations to all of the Cisco Live IPv6 speakers and thanks to all for their great contributions. In case you missed anything and would like to review recordings of any of the content delivered in San Diego (or for that matter at other Cisco Live Events) then do not forget that content is all archived on line:
Cisco Live 365 Content Archive
San Diego content will appear in early July.
I was also involved in an excellent IPv6 Panel discussing “Experiences with IPv6 Deployment“.
This panel had some great external subject matter experts and practitioners including:
- John Jason Brzozowski – Fellow and Chief Architect, IPv6, Comcast Cable
- Rich Lewis – IPv6 Product Manager, Oracle Corporation
- Stephanie Schuller – Global Infrastructure Architecture & Strategy, LinkedIn
- Chip Popiviciu – President and CEO, Nephos6
- Ed Horley – Principal Solutions Architect, Groupware Technology
- Alain Fiocco – Sr Director, IPv6 High Impact Project, Cisco
- Eric Vyncke – Distinguished Engineer, Cisco
- Jon Woolwine – Distinguished IT Engineer, Cisco
The panel are all in the picture below:
Among the many interesting topics discussed were:
- Address management and assignment
- Deployment Best practices
Speaking during the panel Jon Woolwine shared how Cisco rolled out IPv6 internally:
”We were able to absorb most of the cost of our IPv6 deployment by using our existing network lifecycle process to upgrade IOS versions and lay down the proper IPv6 configuration across thousands of network devices”
We asked the audience about the Industry they represented and their specific plans for (and roadblocks to) IPv6 deployment. Some of the feedback captured is shown below. We had a majority of Enterprises in the audience. Over half of our audience had deployed or would deploy IPv6 in the next 18 months with a third of those actually deploying IPv6 within the infrastructure itself.
Later I asked the panel for their personal observations on the session:
Ed Horley observed:
“It is exciting to see the interest in IPv6 that was present in the IPv6 panel session. The questions from the audience were excellent and my fellow panel members had incredible practical knowledge to share. Clearly, there is a shift happening where enterprises are starting to realize the impact that IPv6 might have and are starting to investigate a way forward.”
Chip Popiviciu said:
“The size of the audience, the questions, the interaction and overall energy displayed during this panel highlighted industry’s clear change in perception, interest and prioritization towards IPv6. It is exciting to see IPv6 finally being understood and appreciated for what it really is, a foundational enabler of IT transformation”
Alain Fiocco commented:
“The Internet is now a dual stack global communication system, the debate whether this is going to happen or not, is long over. We did not get questions about “why or when should IPv6 be deployed in my organisation”, it was mainly a discussion about “how”. I believe the audience really appreciated the unfiltered feedback from people who have “done the job” . There is a real sense of urgency, and the realization that it is a lot better to deploy IPv6 on your own terms”
Meet the Engineer was buzzing with meetings (both organised and ad hoc). I had personal involvement in 3 whilst in San Diego. I captured a view of the Meeting Hub area below:
Eric and I also drove IPv6 within the rest of the Cisco Live program. Our span of focus here included:
- Ensuring the event runs on IPv6-enabled web platforms
- Ensuring the event makes IPv6 available to attendees on the WiFi
- Highlighting IPv6 usage in the World of Solutions and DevNet Zones
Leveraging Cisco infrastructures protocols and APIs that support IPv6 including Management, Monitoring, DDOS mitigation, Troubleshooting Configuration and Address Management, Cisco Partners products and solution offerings are critical to help our customers enable and leverage IPv6. Within the World of Solutions over 250 Cisco partners exhibited all that is new and innovative in the networking world and once again we were highlighting IPv6 Enabled demonstrations with the IPv6 Enabled Logo:
We specifically found IPv6 running in many demonstrations including:
This is by no means an exhaustive list of all Partners who enabled IPv6 but these were the ones I personally visited and tagged.
I captured many of these on picture for you to enjoy here.
We also created brand new program for Cisco Live San Diego, which we called IPv6 Ambassadors. The idea was to spread awareness of IPv6 deployment status using the Cisco 6lab site as a vehicle for discussion and learning. Adorned with these cool shirts and jackets carrying the logo of the Cisco 6lab site were a number of my colleagues including Alain Fiocco (rear view !), Tim Martin, Fred Baker and Vernoika McKillop who are shown below:
In total we covered over 39 hours of “Ambassador time” socialising the overall state of IPv6 deployment. Please look for IPv6 Ambassadors in future Cisco Live events.
Cisco Live never stops and is back again in November in Cancun. My personal involvement will resume again shortly as we start planning our content program for Cisco Live Europe in Berlin in February 2016 and of course back in the US in Las Vegas in July where we will continue to raise the flag for IPv6.

Over the last several months, I’ve been pleased to invite Mark Townsley, Cisco Fellow and recognized expert on Internet Protocol (IP), to discuss IPv6 as a key enabler of the Internet of Everything (IoE). In his series of guest blogs, Mark has explained the basics of IPv6 and why it is important (“Demystifying IPv6”), and discussed some of the technical challenges of moving to this latest version of IP (“Moving to IPv6: Rebuilding the Heart of the Internet Without Missing a Beat”). In this installment, Mark takes a look into the future at some of the things IPv6 will make possible. I’m particularly excited about this, because the unlimited addressing scheme of IPv6 is what will enable the exponential growth of connections among people, process, data, and things that will drive $14.4 trillion in IoE private-sector value over the next decade, and dramatically impact our daily lives. This is Mark’s third and final blog on IPv6.
In my last blog, I explored various ways that IPv4 and IPv6 can coexist on the same network —each vital during the global IPv6 transition period, which began in earnest after the World IPv6 Launch last year. Today, I want to highlight new network deployments and designs that I like to call “IPv6-centric.” These architectures go beyond the more conservative approach of a congruent dual-stack IP network. Instead, they are designed and operated from the ground up with IPv6 at the base. While these networks can accommodate IPv4, IPv6 takes center stage.
IPv6-Centric Mobile Networks: Beginning last month, T-Mobile and Metro PCS users in the United States running the latest version of Android software are now provisioned with IPv6 by default, with no IPv4 address from the ISP network. Traffic to IPv6-enabled destinations such as Google, Facebook, Yahoo!, and Wikipedia will simply use IPv6. Traffic to non-IPv6-enabled sites will be translated to IPv4 after traversing the ISP network. If there are any remaining applications on the device that simply do not know how to handle IPv6, the Android device itself performs and IPv4-to-IPv6 translation internally, so the access network doesn’t see IPv4 at all.
“4G speeds and IoE are driving ‘scale-up’ and ‘scale-out’ in mobile networks. The scarcity of globally routable IPv4 addresses forces a series of compromises that an IPv6-only infrastructure alleviates, providing a solid bedrock to build upon.”
— Cameron Byrne, T-Mobile Wireless, USA

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional hardware as traffic grows. Read More »

This week is the industry’s leading IPv6 event, the World IPv6 Congress in Paris, France. Cisco Fellow Mark Townsley delivered the keynote again, this time with a theme around the “Mobile Business Case for IPv6”. What’s exciting is that in the mere 18 months since the World IPv6 Launch we’re already seeing significant adoption of the larger scale address protocol. Mark in fact specifically cites how Verizon Wireless is already sending 30% of its traffic to search engine giant Google over IPv6. Other wireless operators are going straight to IPv6 for 4G and LTE deployments as well. Read More »

This past weekend, Google’s IPv6 Statistics reported that on November 17, 2012, user activity on their websites via native IPv6 reached 1% for the very first time. This may not sound like much at first glance, but for a system like the Internet which is slated to have 19 billion active fixed and mobile network connections by 2016, even one percent of this whole marks an impressive achievement. The billions of applications, devices, routers, and switches that make up the Internet are all interconnected such that if any one doesn’t support IPv6 on a given path between the end user and the content the user is trying to reach, the system automatically falls back to IPv4. This is necessary to keep the Internet running while the upgrade occurs, but it also means that the benefits of end-to-end traffic flow over IPv6 occurs only after all the various links in the chain are all capable of supporting IPv6.
To get a better idea of how each individual piece of the deployment puzzle is advancing, Cisco has been tracking various leading indicators and regional deployment statistics. We’ve pulled these together in an interactive tool at 6lab.cisco.com where you can view IPv6 deployment data from a variety of perspectives. With the tool you can “mouse over” different regions of the world to see how various countries are doing in different areas. For example, by moving your mouse cursor over the United States, you can see that 57% of the networks that appear as transit for IPv4 today also support IPv6, end users as measured by Google is higher than the global average at 1.93%, and that 45% of the time the average user in the US visits an IPv6 reachable website. You can also dig down into the methodology we are using to create the various rankings and percentages.
Moving the needle
Back in 2007 when Google began publishing its IPv6 measurements, native IPv6 deployment stood at 0.04%. Working together, the industry moved the needle 2500% over the past five years (while adding an additional billion users to the Internet during the same period). To help make this happen, two historic industry events have occurred: The World IPv6 Day in 2011 and the World IPv6 Launch in 2012. During the planning stages for the World IPv6 Launch, I had the privilege to work alongside other industry leaders and the Internet Society until agreement was reached to target three categories of participants that committed to enable production-level IPv6 by default: website operators, network operators, and home router vendors. Cisco signed on and participated as both a website operator and home router vendor.
Making a commitment is one thing, allowing a public measurement for all to see is another. For a website it is rather simple to measure IPv6 deployment as either a “AAAA” record for IPv6 exists in the public DNS system and the website can be reached from the Internet over IPv6 or not. For the network operator category we were looking for a lasting commitment together with some measurable factor that would provide reasonable proof that the network had moved beyond trials and on to production-level deployment. After much discussion, we came up with these two basic commitments for this category:
- IPv6 be a “normal part of business operations” for users, targeting ISPs to commit to enable IPv6 for users by default rather than on “special request”
- One percent of all user activity as measured by Google, Facebook, Yahoo! and Bing over IPv6 by June 6, 2012, the inaugural day of the Launch.
In practice, reaching one percent of user activity means deployment to a considerably larger subscriber base than one percent after accounting for legacy home networking gear, operating systems, and applications. For an ISP to reach this level as measured by the content providers, the “general population” of subscribers would have to brought into the deployment – a strong indication of production-level operation and reasonable proof that the deployment was more than a trial of friendly users or beta testers.
The aim of the World IPv6 Launch was to spark a sustained growth of IPv6 usage leading up to and continuing after June 6, 2012. The continued growth since June 6 and the milestone reached this weekend is an indicator that this commitment had its intended affect thus far. The Internet Society is continuing to report measurements for World IPv6 Launch participants, and has been soliciting new members. There are quite a few Network Operators on the list now, including not only ISPs but universities and other types of networks as well. As long as a network has its own Autonomous System number, it can be measured and potentially added to the participant list. Cisco now has its own AS (#109) on the list, making it the first in the world that is participating in all three categories of the World IPv6 Launch.
User activity as measured by Google hit 0.25% for the first time in March 2011. A year later, on March 10, 2012, it doubled to 0.5% for the first time. It’s taken about 8 months to double that again to reach 1.0% today. If this trend continues, it will double again by mid next year and could break past 10% by the end of 2014. The trend is increasingly clear: If you are a network operator, network-enabled application developer, or anyone else that works with IP and are not running IPv6 now or don’t have a plan in place to make it happen soon, now is the time to get started.
