Celebrating New Year 2016 with 10% IPv6!

Every Monday morning, as a matter of ritual it seems, I check the Google IPv6 adoption graph to see the latest numbers. Today, I was thrilled to see it finally top 10%! That means that 10% (10.41% on January 1, to be precise) of the traffic hitting Google’s servers – a pretty good indicator of overall Internet traffic – is coming from an IPv6 connection.

We consider hitting the 10% mark a major milestone. It was just over a year ago that the number crossed 5%, which we reported at the time. It’s taken a little longer than a year to double from that number but still it has doubled in close to a year and that’s a pretty good growth rate. I’m very happy to see that.

We made an ambitious prediction in early 2014 that we would see the 10% mark by the end of 2014. We knew at the time that was an ambitious prediction and it turned out to be wildly ambitious. We were coming off a year of impressive growth in 2013 and it was conceivable that we would see something close to that number. Growth slowed in 2014, but seems to have settled into a steady upward trajectory. For those of you who are statistically inclined, Eric Vyncke has a great tool that allows you to make some predictions about IPv6 growth.

IPv6 deployment is important for the future of the Internet. IPv6 is the protocol that gives us truly global addressing for every device that attaches to the Internet. In addition to all the screens that we use in all aspects of our lives every day now, we anticipate an explosion of other smart devices attaching to the Internet in the coming years. The Internet Society’s recent paper on the Internet of Things just begins to scratch the surface on the IP addressing needs, but it’s an area we expect to have a big impact on IPv6 deployment.

Much remains to be done to see pervasive IPv6 in the Internet. We’ve seen significant broadband deployments across the world, and more recently we are encouraged to see uptake of IPv6 in mobile networks. Verizon Wireless deployed IPv6 early and both they and T-Mobile USA have large IPv6 deployments. It is encouraging to note that the four major US mobile operators now all have measurable IPv6 deployments. In addition, SK Telecom, the largest mobile operator in South Korea, also has a large deployment of IPv6. So IPv6 deployment in mobile networks is also taking hold now.

When Google reports that IPv6 adoption is at 10% from their perspective, it’s another opportunity for operators of network infrastructure connected to the Internet to take note.

My Google IPv6 graph habit is no doubt nerdy, but I’ve been working on IPv6 in one way or another for more than 15 years. It’s great to see it deployed and growing consistently, year-over-year, and to be able to report on that trend over a period of a few years. I look forward to seeing that number continue to increase!

We think 2016 is off to a great start so far. So, what are your plans for IPv6 deployment in your network in 2016? Let us know!


Google IPv6 Traffic Passes 5% – IPv6 Internet Growing Faster than IPv4!

We’ve been watching IPv6 traffic numbers climb ever since World IPv6 Day, and today we’re excited to see that the Google IPv6 traffic graph (pictured above) has crossed a nice round number – 5%. This means that 5% of all traffic globally reaching Google’s servers uses IPv6 as the Internet Protocol of choice. This is great news because IPv6 deployment and use means the Internet can continue to grow!

Even better, there are several countries around the world where more than 10% of the traffic from networks in those countries use IPv6 – Belgium, Luxembourg, Germany, and the US – with several others close to that mark. Akamai reports similar numbers in its global per-country measurements. This is all very exciting progress as we march toward full deployment of IPv6 across the globe.

Earlier this year we predicted double digit IPv6 traffic by the end of 2014. That was a very aggressive and optimistic prediction meant to grab headlines and prompt action, and we didn’t quite make it to that target. In reality, traffic growth this year has been slower than in 2013. I’m happy to see IPv6 still increasing steadily, but of course I wish it had continued along a growth path that looked something like an S-curve. Still, it is growth, and most importantly, it means that the IPv6 Internet is growing faster than the IPv4 Internet.

When I look at the new networks that have been joining the global deployment of IPv6, as reported in our World IPv6 Launch measurements, I’m hopeful that the growth in IPv6 will continue and the rate of growth will increase. We’re beginning to see multiple mobile networks rolling out IPv6 and growth in that realm can accelerate the footprint of IPv6 rapidly.

While 5% might not seem like a large percentage, it’s a big step on the path to IPv6 becoming the prominent Internet Protocol on the Internet, and billions more people and devices being able to connect to an Internet that works like the one we’ve enjoyed and benefitted from so far. And that’s worth celebrating.

IPv6 Traffic and Mobile Networks: Thoughts After World IPv6 Congress

Can we get more operators to share their IPv6 measurements? How many mobile operators are using an IPv6-only strategy for their networks? These were two of the questions we found ourselves discussing when we participated in the v6 World Congress in Paris a couple of weeks ago. I presented updated World IPv6 Launch statistics (embedded below) and actively listened to others in the industry discuss where they were, are, and will be with their IPv6 deployments. After the event, Alain Fiocco wrote a Cisco blog post summarizing the contents of the World IPv6 Congress and important next steps.

I’d like to call attention to two specific aspects of what was discussed there: operator perspectives on IPv6 traffic and IPv6 in mobile networks.

Alain points out that network operators who have turned up IPv6 would like to see more IPv6 traffic, which obviously requires more content being enabled on IPv6. We agree. It would be very helpful for operators to share their IPv6 measurements so the world can see what kind of IPv6 traffic is observed on a v6-enabled network. Martin Gysi of Swisscom last month wrote a guest post for our blog where he described what kind of IPv6 traffic he sees and where it is coming from. We ask others to do the same. If you operate a network that has IPv6 enabled, please share your measurements with the rest of us. It has a great impact on folks considering the timeline for their own deployments to see what to expect when they do enable IPv6.

Alain also called attention to the fact that several mobile operators made public statements about their plans to transition their networks to IPv6 using an IPv6-only strategy with 464xlat to get to content that hasn’t yet been enabled for IPv6. This is the strategy that T-Mobile in the United States is using and we report increased IPv6 traffic in their network each month (18% last month) in our World IPv6 Launch measurements. It is a great method for getting IPv6 deployed in a mobile network with a clear path to alleviate pain from lack of public (and private!) IP address space for growing networks.

I’d love to hear from you if you’re interested in contributing more operator perspectives on IPv6 networks, or if you’re a mobile operator working on your IPv6 transition. Either leave a comment here, or on our Twitter, Facebook, or Google+ channels!


Google IPv6 Traffic Passes 3% – Deployment Rate Accelerates

The Google IPv6 traffic graph (above) is one of the most watched barometers of global IPv6 deployment. This past weekend it crossed another round number – 3%. While 3% might not seem like a large percentage, it’s another step along the path to IPv6 becoming the Internet Protocol used in the Internet.

It’s worth observing that we just crossed the 2% threshold on September 21, 2013. The IPv6 deployment rate is accelerating, since before that it had been almost a year since the measure crossed 1% (on Oct 27, 2012).

What is driving this increase in IPv6 traffic? More operators in more countries are deploying IPv6 and increasing the size of their subscriber base that use the technology. You can see the list of networks that have measurable IPv6 deployments in the World IPv6 Launch. You can also look at the Google country graph of Europe to see that there are substantial deployments in Switzerland, Belgium, Romania, Germany, and France, for example. The IPv6 traffic from Belgium alone has almost doubled in the last month.

We predicted last month that global IPv6 traffic would exceed 10% this year. That’s an aggressive prediction, but from what we see in the measurements and what operators tell us about their deployment plans, it’s definitely within reach.

Prediction: IPv6 Adoption Hits Double Digits in 2014

Last week, I had the opportunity to provide some predictions for 2014 to the Telecom Council of Silicon Valley. I have mixed feelings about predicting the future when it comes to the Internet – the Internet has been such a change-maker that I’ve been known to say, “a predictable Internet is a dead Internet.”

That said, we’ve been watching (and sharing) the data and trends in IPv6 uptake since World IPv6 Launch almost two years ago, so I feel comfortable putting a stake in the ground and proposing:

Prediction: IPv6 will be a mainstream technology by the end of 2014

  • 10% of all global Internet traffic to Google, Facebook, and Yahoo! will use IPv6
  • IPv6 will have additional large commercial rollouts on every continent
  • All major United States network operators will offer IPv6 on a commercial basis to end users

The number (10%) is pretty easy to sketch from Google’s own IPv6 measurements. The amount of IPv6 traffic hitting Googledoubled from 1% to 2% between September 2012 and September 2013. In the 4.5 months since, it’s surpassed 2.75%. The rate of growth is increasing.

So, is 10% traffic toward major content providers enough of a leg to stand on in the claim that IPv6 will be mainstream? I think so, because it’s an important metric for network operators. They watch where their network traffic goes, and when the top five websites (as measured by Alexa) can take their traffic over IPv6, they pay attention. The reason the Google graph is showing that sharpened curve is because more networks around the globe are lighting up IPv6. The top networks (as shown on the World IPv6 Launch measurements page) are spread across the globe – US, Europe, Asia.

Now that IPv6 is becoming a mainstream Internet technology, it’s time to wake up and get IPv6! Are you connected to the entire Internet? (Our Deploy360 Programme can help you get started.)
