I think it's not just 'for sale' but 'gosh /24 really isn't the limit is it? lets start accepting and passing on /25../26../27...etc' Sure it's not going to get to Avagadro's number of prefixes in v4, but 3B is still way more than 2M (which is about where current vendors stop hedging today). In the end, ipv4 can get larger than current platforms can handle, quickly, and future planned platforms as well. It seems that the same problem exists regardless of protocol#. > The RIR's appear to me to be gearing up for this to some degree. yes. -chris
