Another advantage is that you only need one global routable address
for each node instead of "using up" one of them per interface. If you
select non-routable addresses as interface addresses (e.g.
169.254.0.0/16 or fe80::/10), you even keep your routing tables small
because you only need one entry per node (and one per attached network
of course).
