Q: Why are /48s everywhere in the design? A? Because it's a good idea! This kind of crap is one of the reasons people get frustrated with IPv6 zealotry. If people are actually interested in deploying IPv6 then by all means, STOP BITCHING AT THEM ABOUT HOW THEY DO IT. Problems like the wrong allocation to end users are fixable, especially given that the vast majority of end user assignments are dynamic in the first place. The model I've been advocating is for ISPs (who have enough space) to start off reserving a /48 per customer and then assigning the first /56 from it. If after real operational experience it turns out /48 is the right answer, you're all set. If /56 turns out to be sufficient, when you use up all of the first /56s you can start on the first /56 in the second /49, etc.
While I like the idea of /48s per customer ("per-nearly everybody"), I do think this approach is a good, slightly more conservative approach. Regards, Mark.
