Stateless autoconfiguration.
See, that's the classic mistake: Everyone wants to divide the entire
address space RIGHT NOW, without any clue as to how the world will
evolve in years to come. Nature may abhor a vacuum, but it certainly
also seems that engineers abhor unallocated address space, and will try
to allocate everything even when they are lightyears off the mark
About 85% of the IPv6 address space is specifically left unused at this

use *now* just 3/8192th is really used.
