I am way, way behind on my entries and I am sorry about that. I am trying to catch up on IPv6 stuff as I have been blasting away at various Microsoft, VMware and Cloud projects.
On vacation last week I tried to get caught up on some reading and watched some archives of the recent NANOG meeting (NANOG 46 in June 2009 http://www.nanog.org/presentations/archive/index.php) – yes sadly enough I do this on vacation. I viewed Dave Ward’s interestingly titled talk “It’s The End Of The World As We Know It (aka “The New Internet Architecture”)” – http://bit.ly/QOAVg. Dave had many good observations and I agree with many of his comments except one – “Dual-stack transition to IPv6 abandoned”. As someone who works with enterprise customers each and every week for IPv6 design and deployment I can safely say that dual-stack is alive and well and IS the most “pure” way of IPv6 deployment that we have today. Yes, there are operational and even security and performance challenges with running two stacks simultaneously but until something better comes along, dual-stack is all we have that gets us away from tunnels.
I know Dave is not arguing one way or the other but simply stating his views on where things are and where they may go and that is cool but I feel it is a bit radical to state that the number one methodology for IPv4/IPv6 co-existence is abandoned.
What are your thoughts on various co-existence mechanisms TODAY vs. what is being proposed by the IETF for the future?
