Ah, I follow your reasoning. I'll be interested to learn whether the
numbers agree. ARIN staff has reported before that the vast majority
of IPv4 end user assignments go to organizations which do not
subsequently return for additional assignments. In general it's the
ISPs who come back for more allocations... I wonder if the minority of
end-user orgs who do request additional space request enough
additional blocks to make a difference in the routing tables.
