There are other analysts (myself among them) who anticipate the number of 
North Amercan ISP's to grow by a third this year from around 2,000 to 
around 3,000. Yes, there is some consolidation, but this is very little 
in relation to the entry of new ISP's into the market. As long as the 
Internet is growing exponentially, there will be room for new entrants 
and we will not be seeing an absolute decline in the number of ISP's.

Think exponentially, plan accordingly ;-)

In other words, CIDR, PIER, and RFC1918....
