It falls on a 16 bit boundry and is therefore easy to read. some
numbering concessions within a vast space exist for the convenience of
the poor humans not the machines. I can pick out the host side of the
address in a /64 no problem but for some reason I have a trouble finding
subnet boundaries on a series of /93s.
