Landmark IPv6 Report Published: State of Deployment 2017

On the fifth anniversary of World IPv6 Launch, we’re excited to share a detailed report on the State of IPv6 Deployment in 2017. It really is staggering how far IPv6 deployment has progressed in five years. In mid-2012, Google measured less than 1% of users accessing their services over IPv6. Today that figure is getting close to 20%. Since World IPv6 Launch, several major operators are now delivering the majority of traffic from major content sources like Google, Akamai and others over IPv6. Individual operators, like T-Mobile USA, have deployed IPv6-only networks for their subscribers.

Six years ago, the Internet Society helped to organize World IPv6 Day, where thousands of ISPs and websites joined together for a successful, global-scale, 24-hour trial of IPv6. A year later, for World IPv6 Launch, major ISPs, home networking equipment manufacturers, and web companies around the world permanently enabled IPv6 for their products and services.

report cover imageHow much progress have we made in the five years since World IPv6 Launch? All the details are included in our landmark report marking the launchiversary. While you download the report and check out our other IPv6 materials, here are the highlights:

  • IPv6 has increased 3000% since the beginning of World IPv6 Launch five years ago.
  • Deployment is occurring around the globe: Measurements show 37 countries exceed 5% of traffic is IPv6 to major content providers.
  • Over 25% of the Alexa Top 1000 websites are reachable using IPv6.
  • Some networks are now IPv6-only internally (e.g. JPNE, T-Mobile USA, SoftBank), and some major networks are now majority-IPv6 (e.g. RelianceJIO, Verizon Wireless, SkyBroadcasting, XS4ALL).
  • Some organizations are in the process of turning off IPv4 within their networks and/or data centers to reduce network complexity and cost (e.g. T-Mobile, Facebook, LinkedIn).
  • The Internet Society’s core recommendations are to: (a) start now if you haven’t already, (b) use established RFP requirements like RIPE-554: Requirements for IPv6 in ICT Equipment, and (c) take advantage of existing IPv6 deployment information including the Internet Society’s Deploy360 Program.

IPv6 use is set to continue growing for the rest of this year and beyond as more operators start and grow their deployments around the world, and new content and hosting providers enable IPv6 for their customers. As we mark this milestone in IPv6 deployment history with this new landmark report, we wish all our readers a Happy Launchiversary!

SixXS to close down

It was recently announced by the founders of SixXS that the service will be closed on 6 June 2017.

SixXS is a IPv6 Deployment and Tunnel Broker service that started back in 1999 with a view to providing a way for network operators and users to gain experience of IPv6, and to encourage deployment of IPv6 in the real world.

The founders Pim van Pelt and Jeroen Massar now believe SixXS has achieved many of its original objectives with native IPv6 having become more widely available. Whilst SixXS has experienced declining uptake since 2011, this should be viewed positively as it has gone hand-in-hand with increased IPv6 adoption by production networks and particularly content providers.

SixXS has brought IPv6 to over 50,000 users in more than 140 countries, with 65 servers hosted at approximately 40 network providers. It has also contributed towards solving the chicken-and-egg problem whereby content providers would not invest in IPv6 whilst ISPs were not offering it, and ISPs would not offer it whilst there were no IPv6 resources. By providing users with IPv6 connectivity, it has encouraged the major content providers such as Google, Facebook, LinkedIn, Akamai, Netflix, Microsoft, Yahoo and Wikipedia to offer it, which is making it harder for network operators to argue a lack of demand.

The founders feel the existence of IPv6 tunnel brokers is now providing a disincentive for network operators to deploy native IPv6, which is another reason for deciding to close the service.

SixXS recently undertook a survey of the IPv6 rollout plans of network operators, and users are encouraged to continue press for IPv6 where their operators has no plans for rollout.

Deploy360 would like to acknowledge the founders and supporters of SixXS for their efforts to promote and deploy IPv6 over the past 18 years.

We would also like to encourage you to deploy IPv6, so please check our Start Here page for more information!


IPv6 in Finland – finally

Today, 9 June 2015, is national IPv6 launch day in Finland. Some people might raise their eyebrows and ask: “what, again?” I remember organizing an Internet Technology conference in Helsinki in 1999 where one of the topics was IPv6 and its imminent worldwide deployment. After that it soon started to resemble the story of the boy who cried wolf and “IPv6 will come next year” became a running joke.

So, sixteen years later, has something changed? A couple of months ago I would have said not really. However, the Finnish Communications Regulation Authority’s approach to organize a national launch day and get all the big players to take part seems to have worked. Last month the statistics on the Finnish IPv6 deployment were still showing really low figures – on average less than one percent of all traffic was on IPv6. Today it is estimated about 4 to 5 percent. According to Emile Aben from RIPE NCC, “it’s rising like a rocket”.

And why not? It could be argued that this is long overdue. Public IPv4 resources were exhausted along time ago in Europe and we can read from the news how IPv4 addresses are sold to the tune of 5 euros a piece for the desperate.

At the moment is seems that the snowball has started rolling and is gathering both momentum and size. Hopefully it will keep growing and not melt away in the summer heat.

NIST’s Excellent Guidelines On How To Securely Deploy IPv6

Looking to understand how to securely deploy IPv6? Want a document you can provide to your security team or others concerned about IPv6?

If so, we’ve recently added to our list of resources an excellent “Special Publication” from the U.S. National Institute of Standards and Technology (NIST):

Guidelines for the Secure Deployment of IPv6

Like most of NIST’s special publications, including their excellent guide to DNSSEC, the document begins with a lengthy tutorial and then walks through a number of IPv6 security issues in great depth. It’s a very thorough document and includes detailed sections on the many different IPv4-to-IPv6 transition mechanisms as well as detailed appendices.

While the document naturally includes sections providing guidance for US federal agencies, the majority of the document is very applicable for anyone looking to understand issues of IPv6 security.  Well worth a read… and worth passing along to others who may be asking you questions about IPv6 security.
