I have several corporate customers with B's. Most of them got the
addresses
well before connecting to the Internet. These are medium to small
firms.
I've got huge clients existing on much less.
There is a LOT of space that needs to be harvested from inefficient
allocation. ISP's need to be the leaders of efficiency. If we were to
do our job correctly, those inefficient allocations should be able to
be eliminated in a painless manner... no one should have to renumber.
NAT has it's flaws, but sooner or later we will all be using it. ISP's
should be able to maintain their own address space consisting of as many
full address spaces as they feel like translating. Part of what we need
is better central site software and systems, but that is coming.
I'm confident the world will never run out of ip addresses. When we
think
we are out, we will learn to multiply. It is really a simple
engineering
problem.
There are no limits except those in our heads.
