Migrating Applications To IPv6
A book from Dan York published by O'Reilly
Updates Submitted For “Migrating Applications To IPv6″ Book
May 3rd
Very early this morning, I submitted a range of updates to the book to O’Reilly’s production team. As this is the first formal update I’ve made, I’m not sure of the exact process from here, but at some point soon the updated content will be available as part of the normal book. I’ll post about it here on the site when it’s ready, and anyone who bought the ebook directly from O’Reilly will be automagically notified about how to download the updates.
Here’s a snapshot of the changes I made to the book:
- Added new section on recent events and changes that make it critical for application developers to be thinking about IPv6.
- Added section on connecting to DNS servers over IPv6 and about DNS and DHCPv6
- Added sidebar about RFC 5952, “A Recommendation for IPv6 Address Text Representation”
- Expanded text about “Happy Eyeballs” algorithm and included mention of RFC 6556 for testing for happy eyeballs.
- Added brief info about lessons learned from World IPv6 Day
- Added info about World IPv6 Launch in 2012
- Added new section on testing resources
- Added new section about setting up an IPv6 test network
- Updated IPv6 NAT info to point to RFC 6296
- Added warning about SMTP’s way of showing IPv6 addresses
- Added additional resources, including a new section about some informational RFCs that may be of interest to application developers.
I’m pleased with how it came out… there’s been a great amount of new information added in the last few months that will be helpful for application developers and it was great to incorporate that into the book.
Next up, I’d like to add some images that illustrate some of the points in the book… but that’s the next update…
… and please do let me know if you have suggestions for additions you’d like to see in the book, either as a comment here or via email.
50% Off Four O’Reilly IPv6 Ebooks Through April 16, 2012
Apr 9th
The good folks at O’Reilly have now launched a deal where you can get 50% off of four IPv6-related ebooks, including my Migrating Applications to IPv6 as well as the critical IPv6 Essentials from Silvia Hagan. The deal is only good until April 16, 2012, though!
“Migrating Apps To IPv6″ Ebook Now Available in Kindle Fire (KF8) Format
Feb 21st
If you use the Amazon Kindle Fire to read ebooks, the folks at O’Reilly have now optimized all their ebooks to work with the new “KF8″ format used by the Kindle Fire.
When you login to your Oreilly.com account and look at your purchased ebooks (or if you buy the book from O’Reilly), the “Mobi” file there is now a KF8 file that you can download to your computer and upload to your Kindle Fire (or any other Kindle).
Now, I don’t know that I’ve necessarily done anything to the text of “Migrating Applications to IPv6” that would strongly benefit from the new KF8 format (nor do I have one to try it on), but these regenerated Mobi files may in fact display better now on the Kindle Fire. Regardless, it’s great to know that the publisher of the book is looking at what can be done to make the books work better on newer devices.
The world of ebook publishing is at a fascinating place right now… and given some of the experiments O’Reilly is doing I’m looking forward to writing more of these updates as we all collectively continue to evolve this thing-formerly-known-as-a-book!
World IPv6 Launch Coming On June 6, 2012 – Will Your Apps Work with IPv6?
Feb 13th
On June 6, 2012, World IPv6 Launch will mark the time when IPv6 is permanently enabled by many operators, website operators, content providers and organizations around the world.
Will your application(s) work on IPv6? What will you need to do to make sure that your apps work as well on IPv6 as on IPv4?
The main point of the book was to help you think through the questions and look at what you need to do.
Will you be ready?
Google+ Page Now Available for “Migrating Apps To IPv6″ Book
Nov 8th
Are you on Google+? If so, please consider adding the Google+ Page for this book, Migrating Applications to IPv6, to one of your circles. (Hmmm… maybe one called “IPv6″? or “Books”?)
I’ll be honest and say I’m not 100% sure yet what I’m going to do with that page, but I’m thinking that I’ll experiment with it as an adjunct to this blog for communication with readers and others about the book. It is also quite frankly a way to experiment with the new “Google+ Pages” that were released yesterday.
If you’d like to join me in the experimentation, please do so!
P.S. And naturally I have my own (Dan York) regular profile on Google+. Please do feel free to add me to one of your circles.
First Update Started To “Migrating Apps to IPv6″ – Any Further Feedback?
Nov 4th
After moving through a job change and reaching a steady state with a family medical issue, I’ve finally got some cycles ahead of me to get back to something I’ve wanted to do for several months now… get an update out to this book!
I’m currently writing more text and am looking to do the following to the book in this update:
- Add a few more graphics to illustrate points, particularly the “happy eyeballs” concept.
- Expand coverage of the “privacy address” issue.
- Expand on the issues around Carrier-Grade / Large-Scale NAT.
- Add in some of the lessons from World IPv6 Day on June 8th.
- Add examples / case studies from people who have gone through the migration of their app over to IPv6.
On this final point, I have a few developers who I am contacting to see if they are willing to share their story, but I am definitely open to including more case studies. If you have migrated one of your applications to work on IPv6, I’d love to hear from you.
Beyond this list, do any of you have other points you would like to see included in the book? Or areas in the book that you would like to see expanded?
Please either leave a comment here or drop me an email to let me know. Thanks!
I’m not sure of the exact timeframe but I’m hoping to get an update out by the end of November.
P.S. Note that any of you who bought the ebook directly from O’Reilly will be automatically notified when the new version is published online.
Time Warner Cable Seeking More Volunteers for Residential IPv6 Trials
Sep 28th
If your cable company here in the USA is Time Warner Cable and you get your high speed Internet access through them, they are looking for more volunteers for their residential IPv6 trials. This message below went out yesterday to the NANOG mailing list:
Time Warner Cable is expanding our residential IPv6 trials in several markets, and we need more people. If you’re a Time Warner Cable High Speed Internet subscriber, and are interested in participating in our IPv6 trials, please let us know! We have a short form at
http://www.timewarnercable.com/Corporate/support/IPv6_volunteerform.html
that will help us find the right mix of people, equipment, and locations, to get the most out of our trials.
Thanks in advance for participating!
As a Time Warner Cable subscriber, I immediately headed over to complete the form. My whole home office uses IPv6, but it’s through a tunnel out to Tunnelbroker.net and while that works okay, I’d love having native IPv6.
Now, whether or not little old Keene, NH, qualifies as one of the “several markets” to which they are expanding their trials remains to be seen…

You get an email with a link and you can just click through to download the new copy. Alternatively, you can visit your product portal on your mobile device and download the new version directly to your device.
This last point is key… as I create updates for the book with more IPv6 migration information, you’ll get the notifications directly.
Anyway, if you are interested… the sale to get the ebook at 50% off only runs until the 28th!
Looking For IPv6 Application Migration Case Studies To Include In The Book – Care To Share Yours?
Aug 12th
As I have continued to talk and speak about IPv6 and issues around migrating applications over to IPv6, one of the themes that has repeatedly come up is that developers are looking for examples of people who have gone through the migration from which they can learn.
Understandably, they’d like to know what pain – or NOT – other developers had to go through to migrate their app to work on IPv6.
With that in mind, I’m thinking of adding a new section to the book with specific case studies around apps that moved successfully into a IPv6/IPv4 world. Basically capturing what the developers did or did not do, what they had to change, how their application needs to be configured to work with IPv6 (if it does), etc., etc.
I have several companies and individual app developers that I will be contacting to include, but the beauty of an e-book is that there really isn’t a limit on what I can include in terms of length. So…
IF YOU HAVE MIGRATED AN APP TO IPv6, I’D LOVE TO HEAR FROM YOU!
I have some questions I’d like to ask you about what you’ve done, the challenges (or lack thereof) you encountered, etc. I expect that an email exchange is all that is needed, although if you are interested I’m toying with maybe also doing some video interviews as well (typically via Skype video).
Please do contact me if you’re willing to share your experience. Working together we can build a compilation of case studies that can help more people make the move to IPv6! Thanks!
I am NOT Speaking at OSCON Friday About IPv6
Jul 27th
Sadly, I will not be speaking about migrating applications to IPv6 on this Friday, July 29, at OSCON 2011 up in Portland, Oregon. Instead, my colleague Adam Kalsey will be presenting the talk on my behalf. (Adam is also speaking about managing open source releases of a cloud platform.)
As I wrote in the beginning of the book, it was my proposal to OSCON (which was accepted and scheduled) that prompted O’Reilly editor Mike Loukides to contact me about writing what become the book “Migrating Applications to IPv6“.
In a cruel twist of fate, though, I am now unable to attend OSCON and give the very presentation that prompted the book. Shortly after signing the contract to write the ebook a few months ago, my wife was diagnosed with very early stage breast cancer. While she has now “survived” this bout of cancer, she is still in recovery from the operation, is still in pain and still has a limited range of motion and ability to lift objects. Most importantly, she still can’t really lift our 2-year-old daughter… and, as anyone who has had a 2-year-old can attest, they frequently need lifting! So this year my place needs to be here with her…
While I’m sure Adam will give a great session on Friday and while I may be doing a follow-up webinar with O’Reilly, I would have loved to be out at the über-geekfest that is OSCON! For those who are there, I hope you have a great conference – and perhaps I’ll see you there next year!
P.S. And I am greatly appreciative to Adam for covering my presentation!
