if you can do math, compare the size of a /64 to the entire v6 address
space and then compare the size of even a /32 in v4 to the entire v4
addressing space.

no offense meant - i also dislike address space wastage - but assigning
/64 for non ptp link networks is the least thing that would come to
my mind when i think about address space wastage in v6.
