You are of course correct- I misread "The minimum assignment size is
/48" in terms of prefix length (ie minimum of /48- could be /56, etc.)
which is not what was meant. The very next sentence should have
clarified that for me but I probably skipped over it. mea culpa.
I'm looking forward to seeing a realistic justification from an end user
for more than a /48 :)
As an aside- what is the address block for PI end user assignments from
ARIN? (I can't seem to find it and 2005-1 only mentions a "distinctly
identified prefix" without any mention of what that would be).
The Microallocation blocks are:
Internal Infrastructure: 2001:0506::/31
Exchange Points: 2001:0504::/31
Critical Infrastructure: 2001:0500::/30
(all of which are /48's so far).
But I see no mention of end-user assignments (unless they fall into one of
the above categories- though I don't see how).
