Of course, note that the real problem isn't the memory space, it's the
CPU time to calculate the routing table updates.  Note, too, that the
more unaggregated prefixes in the net, the more changes will need to be
propagated to every other router in the default-free zone, implying the
need for more instances of a more expensive calculation.

Not trying to teach a mailing-list full of grandmother's to suck eggs, but
IFF all 2^32 (-1?) addresses were routed as hosts, then there is no index,
and a linear lookup cost. Stupid thing to do, but a 2^32 * 1 or 2 bytes of
linear address -> interface table.
