Sorry, but I disagree on that. A /56 is fine for today's requirements, but if this hype about the "Internet of Things" really takes off and you want to put things into different subnets, a /56 may occasionally be a problem even for consumer households. Not today, but think anything from ten to fourty years.
We'll have bigger problems, and other problems in 10years time. We have probably start to use more than the 2000::/3 space for one thing. That might change the game?
If we need to start another /3 in just a decade's time then Internet growth will have been astronomical. There are currently 506 /12s available in 2000::/3 and to have allocated them all in a decade would mean allocating more than four per month. Even at a relatively sparse allocation density that would still require an Internet significantly more massive that what we currently have. Regards, Leo Vegoda
