The RIPE NCC gives out /32s to ISPs, but they actually reserve a /29. 
This means they have to get a new /23 for every 64 ISPs that request v6 
space. I imagine this gets old fast after a while.  :-)

What I don't get is that they made it 16 /23s rather than one /19. (And 
staying on 4 bit boundaries would also seem like a slightly more 
obvious choice.)

Not 20 times obviously... But the ARIN region does very little v6, 
while in Europe there are many more small ISPs than in Asia, which 
leads to a larger number of assignments/allocations.
