And don't forget, if they had asked for address space back in
1988-1990 they would be announcing a /16, and using a /24 of it.

The average routing announcement has gotten smaller as a result
of tighter allocation policies.  The use 80% rule and all that.

Of course all the growth is in small prefixes.  You can't get a 
large prefix these days, and if you get a smaller one that should
be aggregatable to a larger prefix next time you ask the likelyhood
it will still be there when you ask for it is low.
