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.
