if you read the ARIN statement on IPv6, you will find that Keith is describing the story of how to cook a frog. soon, (pick your favorite study) all IPv4 space will be allocated. For folks who need IP access after that time, IPv6 will be available. Its those (ones and twos) who will need to access you email and web sites over IPv6 (or via the IETF depricated NAT-PT or other ALG)... It won't be a massive sea-change, it will be a gradual shift. Those not prepared will see a gradual leveling off of traffic/load - as the IPv6 only clients find other places to go to get the services, capabilities, and features that they desire. so in general, I think that Thos might be on to something. --bill On Fri, Jan 18, 2008 at 11:46:19AM -0500, Keith Moore wrote: > I think that's a pretty bizarre way to measure IPv6 deployment.
