New “State of IPv6 Deployment 2017” Shows 3000% Growth over 5 Years

State of IPv6 coverIn the 5 years since World IPv6 Launch, IPv6 deployment has grown over 3,000 percent! Now there are over 37 countries with more than 5% deployment of IPv6. In the USA, where I live, IPv6 deployment is up over 30% … sometimes close to 35%.

These are all statistics out of the new “State of IPv6 Deployment 2017” report published by colleagues of mine at the Internet Society on this fifth “Launchiversary” of World IPv6 Launch back in 2012.

A key point in the document is that enterprise networks are often the ones lagging farthest behind in deployment of IPv6. Mobile networks are far ahead in many locations, and residential broadband networks are also often very far behind.

One reasons some enterprises struggle is that they have custom applications that need to be migrated to work on IPv6. That was really the reason why I originally wrote this very short book back in 2011 – to help developers understand what they need to be thinking about to move their apps over to work on IPv6.

There are many more resources available in the time since I first wrote the book, including ARIN’s guide on “Preparing Applications for IPv6“. The key point coming out of this “State of IPv6 Deployment 2017” report today is that the time is now to make the move to IPv6!  Start the migration… NOW!

If you are trying to get your management or others in your organization to move ahead with IPv6, download this State of IPv6 Deployment 2017 report and send it around – or send the link around. Hopefully the information inside can help you make the case that the time to move to IPv6 is NOW.

IAB Warns That Internet Standards Will No Longer Be Based on IPv4, only IPv6

Internet architecture boardThis month the Internet Architecture Board (IAB) provided another reason for organizations to think more about migrating their applications and services to IPv6. In a strong statement, the IAB warned other standards development organizations (SDOs) that future standards from the Internet Engineering Task Force (IETF) may no longer support IPv4:

The IAB expects that the IETF will stop requiring IPv4 compatibility in new or extended protocols. Future IETF protocol work will then optimize for and depend on IPv6.

This will not happen immediately, of course, but the IAB statement notes that levels of IPv6 deployment are increasing and that SDOs need to ensure that current and future standards can work in an IPv6-only environment.

The key point for organizations and companies with applications is that you need to be seriously thinking about ensuring that your apps can work in IPv6-only networks.

To prepare, I would of course welcome you to buy the book, but there are also resources available online that can help you get started. The important thing is to get started NOW!

4th Anniversary of World IPv6 Launch Provides More Reasons To Migrate Apps to IPv6…

World IPv6 Launch logoToday is the fourth anniversary of World IPv6 Launch, where in 2012 thousands of websites and hundreds of networks permanently enabled IPv6.  I wrote about this anniversary over on CircleID and prominently mentioned that Google’s global IPv6 statistics just went over the 12% mark this past weekend.


Up from 1% just 3.5 years ago (end of 2012). That’s a very remarkable growth rate and a clear sign that the transition to IPv6 IS happening, no matter what critics may say!

Coupled with the fact that as of June 1 Apple is now requiring all iOS apps to work on an IPv6-only network… the situation is definitely clear that application developers need to understand how to make their apps work over IPv6 – and sooner rather than later.

This book was obviously written to help, but there are other resources available now to help developers.

The key point is to get started now! Before that 12% becomes 25% or 50% … and your app that only works on legacy IPv4 networks starts to have more challenges.  Do it today!

Verizon Wireless At 56% IPv6 In Latest World IPv6 Launch Measurements

Some amazing percentages of IPv6 deployment in the February 2015 World IPv6 Launch measurements. As I wrote about on the Deploy360 blog, Verizon Wireless now is showing 56% IPv6 deployment and T-Mobile USA just crossed over 50% IPv6.

Verizon Wireless IPv6 %If you read the notes on the bottom of the measurements page you can see that Google, Facebook, Akamai, LinkedIn and Yahoo! are all measuring the amount of the amount of IPv6 they are seeing to their sites and reporting that back to the World IPv6 Launch project.

The key point for application developers is that all those people on those networks will be able to natively connect over IPv6 – if your application works over IPv6.  

And a reason for caring may be… speed!

If a network is deployed with IPv6 in the main network, as I understand T-Mobile USA has now done, then connections from IPv6 clients can do directly to IPv6 servers.  But connections to legacy IPv4 services will need to go through a gateway.  Gateways typically introduce some degree of latency / delay, even at a microscopic level.

If your application works with IPv6 then you won’t need to worry about any v6/v4 gateways with any potential delays.

The reality that these measurements show is that IPv6 is very real today – will your app work over IPv6?

P.S. the goal of this book is to help! 🙂

IPv6 Statistics Show Continued Growth – Have You Migrated Your Apps Yet?

IPv6stats–GoogleIt is fun to watch the various IPv6 statistics sites because they continue to show the amazing growth of IPv6 around the world.  The World IPv6 Launch measurements now show Verizon Wireless’ network at 59% IPv6, T-Mobile USA at 43%, AT&T at 25%.  Google’s IPv6 statistics show that traffic into Google web sites globally is about to hit 5%.  And then today Akamai launched new IPv6 trend charts that show IPv6 traffic out of Belgium at 29.2%, from Germany 12% and from Luxembourg and the USA right at 10% with Peru not far behind.

All of this shows that IPv6 deployment is very real!  If you haven’t started migrating your applications so that they will work over IPv6 in addition to IPv4, why not?

Obviously I’d encourage you to buy the book to help understand what you need to do… but you can also view the many IPv6 resources out there on the Internet to learn more!  The key point is that you need to get started NOW!  IPv6 is being deployed globally – will your application work over IPv6?

New IPv6 Case Studies Out… But None From Application Developers!

World Ipv6 LaunchAs part of my job at the Internet Society Deploy360 Programme, we recently published a whole new batch of IPv6 case studies during the 2nd “Launchiversary” of World IPv6 Launch. However, if you scan down that list of case studies you’ll see one interesting omission:

There are NO case studies from application developers!

None. Zilch. Zero.

This needs to change!  If you are an application developer and have migrated your application over to work on IPv6, my colleagues and I at the Internet Society would love to write up a bit about what you have done.  PLEASE CONTACT US!

It doesn’t have to be anything gigantic.  It could just be a simple article explaining what you did to make your application work over IPv6.  Or it could be a paragraph linking to a video of a presentation you gave or a set of slides.  We are glad to “interview” you, too, via email or a voice/video call to capture information that we will then write up.  All we need is your interest and willingness to be included.  Please do let us know.

Separately from that, I am still interested in including some case studies in the next version of this “Migrating Applications To IPv6” book that I’m targeting for early 2015.  I have a list of questions that I’d like to ask some of you and include in the book. The benefit to other developers will be that they will get to learn about how to move to IPv6 based on your experience. The benefit to you is that I’ll mention your application and name and give you the added publicity from being in the book.  The benefit to the Internet is that we’ll get more people moving over to IPv6 sooner rather than later!  If you are interested in being considered for the book, please contact me directly!

What IPv6 Migration Questions Would You Like To Know From App Developers?

Question markWhat questions would you like to ask of developers who have successfully migrated their applications to IPv6? What tips and tricks would you like to learn?

I am planning to update “Migrating Applications to IPv6” this summer to include pointers to some of the newer RFCs and transition tutorials and in doing the update I would like to add in mini-“case studies” of applications that have already made the transition to IPv6. Some of the questions I’m thinking of asking developers include:

  • How easy or difficult was the migration to IPv6 for your application?
  • What was the most challenging aspect of the migration?
  • Were there any specific tools or libraries that proved to be the most helpful?
  • Did you encounter any surprises in terms of IP address dependency? i.e. places in your code where you didn’t realize you depended upon an IP address?
  • Did you have to make any significant changes to the way you store information? i.e. configuration files, databases, etc.
  • How did you test your application in an IPv6 environment?
  • Does your app work in both an IPv6-only and dual-stack environment?
  • Is there anything you wish you’d known before you started the move to IPv6?

Do you have other questions you would like me to ask? If so, please either leave a message for me here on the site or on one of the social networks where I post this message – or send me an email.

I would also be interested to hear which of these questions above are the most important to you. What are your top 2 or 3 concerns about migrating your app to IPv6?

Also, if you are an application developer who has already ported your application to IPv6 and would be interested in being a case study in the updated book, please contact me as I am looking to get started on these updates soon.

On that note, I’m also thinking about perhaps creating some interviews in video and audio form related to these questions above… so if you would be interested in some multimedia exposure for your application please let me know that, too. (Thanks!)
