Slides from RIPE66: Making an Application Fully IPv6 Compliant

Today at the RIPE66 meeting in Dublin, Ireland, Bert Hubert of PowerDNS fame gave a great presentation about “Making an application fully IPv6 compliant“:
Slide: Making an application fully IPv6 compliant

The video and audio for the session should be available soon. I very much enjoyed Bert’s presentation and he had a few points that I will think about adding to the next version of the book. One specific point is around collecting statistics. Bert noted that in IPv4 you again typically only have one IP address to worry about for each connection, while in IPv6 you may have many different IP addresses for a connection (or you could have). And so you may need to think about your storage of all that statistics information.

I only had two minor quibbles with Bert’s slides:

  • On slide 11, Bert suggests there could be several different ways of displaying IPv6 addresses with port numbers.  As I stated in the question time, RFC 5952 states that it should be Bert’s choice “a”.
  • On the issue of how to choose whether to use the IPv6 or IPv4 interface, the “Happy Eyeballs” technique defined in RFC 6555 is one that many developers are now using.

Overall, I was very glad to see Bert’s presentation out there as we need to have more such presentations helping application developers think about these issues of migrating to IPv6.

P.S. If you want to easily refer people to Bert’s slides, he provided the very easy URL of:


I am NOT Speaking at OSCON Friday About IPv6

Oscon LogoSadly, 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!
