What is it and what does it have to > do with IPv6? It was a term Keith Moore used to describe the addition of ipv6 capability to NAT devices. Not intended as a real term, merely a marketing name to explain to the end user the benefit of having ipv6 capability. If address space does indeed burn that quickly, ISPs will start to realize they can't sell additional IP addresses as a way of making a quick profit. Those with dwindling address pools will begin to demand proper ipv6 support from router vendors to offer it at a discounted price (compared to ipv4) to their customers who are savvy enough to want to run servers but too cheap to buy ipv4 space at a premium. From there it should only be a matter of time. If key applications work with ipv6 that will probably be adequate to get the ball rolling. IIRC there was a similar transition back when virtual web hosting meant blowing an ip address for every extra domain. After an adequate number of browsers were upgraded hosting providers made available ip-less virtual hosts at a heavy discount from ip-burning ones. After a surprisingly short amount of time the vast majority of browsers were compliant. The final nail was registries refusing virtual hosting as an excuse to justify allocations. That's not news to most here, but I definitely see the similarity in the situation. Austin _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
