I know this may seem a bit premature for most users, but it is coming and perhaps sooner than we think. The link below is one of the best tutorials I've found on You Tube so far. It has a useful review of ipv4 for anyone not clear on that and it does a very nice job of introducing the fundamentals of ipv6.
I am in the process of setting up double stack and tunneling to transition to ipv6 on my network and there be a lot of ipv6 discussion coming up on the Cyberfrontiers podcast going forward.
