This...in my opinion is THE biggest issue that impacts the v6 ability to
achieve the 2 objectives it most needs to accomplish..... Easy
administration without renumbering or returning for more....AND relatively
conservative allocations.

2^48 seems like a reasonable number of interfaces to exist on a single
subnet, huh? Then.... allocate 16 bits for subnetting if it must be....and
call that /64 the fundamental minimum allocation.
