> I actually agree with Bob that the abstract to 6346 says something > that's not true this is the paragraph bob quoted We are facing the exhaustion of the IANA IPv4 free IP address pool. Unfortunately, IPv6 is not yet deployed widely enough to fully replace IPv4, and it is unrealistic to expect that this is going to change before the depletion of IPv4 addresses. Letting hosts seamlessly communicate in an IPv4 world without assigning a unique globally routable IPv4 address to each of them is a challenging problem. please point out what is not true about that paragraph. other than the tense, of course; the iana pool ran out; as have apnic, ripe, and soon arin. the first step in solving a problem is admitting we have it. randy
