Re: Big providers use NAT to squeeze little ISPs

  I will restart my question as such:

  It is my understanding that;

  One of your principal objections to NAT boxes is that they are
  motivated by technical and trade practices you find dishonest.

  Please define and expound.

My principal objection to NAT is that it breaks lots of things, including
some servers, that customers want to put on their networks.

At the PROVIDER level, especially at the level we run at, there is no NAT
box made fast enough to do the job regardless of price.

  Do you really think that big ISP puts in /19 filters to make life
  hard for the "little guy" at the bottom of the "money pile"?

  -alan

As long as a provider can get their own /19 I have no problem with
prefix filtering at the /19 level.

The problem comes about when big ISPs filter at /19s *AND* the allocators 
of space refuse to give ISPs /19s.
