Yes CIDR is a good thing...unfortunately, it does not guarantee that the
net will grow and aggregate in a rational way. When coupled with the
"slow start" ISP policy, CIDR helps to rapidly fragment the IP address
space and in some cases causes poor IP address utilization all in the
name of "protecting the future of the Internet" or maybe "protecting the
Internet from ISPs".
  [...]

It would appear that there may also be a strong argument that the
tremendous proliferation of [small] ISPs is a significant contributor
to the growth of the size of the Internet routing tables.

Perhaps, the [anticipated] consolidation of ISPs will be a significant
event in the efforts to control routing table size.

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 :wink:

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