A /32 is the value that a start-up ISP would have. Assuming that there is a constant average rate of startups/failures per year, the number of /32's in the system should remain fairly constant over time. Every organization with a *real* customer base should have significantly shorter than a /32. In particular every organization that says "I can't give my customers prefix length X because I only have a /32" needs to go back to ARIN today and trade that in for a *real block*. There should be at least 10 organizations in the ARIN region that qualify for a /20 or shorter, and most would likely be /24 or shorter. As Owen said earlier, proposal 121 is intended to help people through the math. Please read the proposal, and even if you don't want to comment on the PPML list about it, take that useless /32 back to ARIN and get a *real block* today. Tony
