Well by the looks of things ARIN, RIPE and APNIC are working their way
though about a /8 each every year or so. This means that Class C space (as
such) is going to be used up in a year or two (only 220-223/8 is
unallocated).

There are still over 60 /8s unallocated after that which means we aren't
going to run out for a few years. When the numbers for broadband start
working however things could quickly get tight.

Still it's a bit off when Defence Establishments have /8s and probally a
minimal number of world visable networks while medium sized countries have
less.

A quick check shows that the following /8s have little or nothing of them
advertised into the global routing table. Of course there are probally a
few others that have the /8 ad and almost no actual use.
