Oh well. Yep. That is the main point for me! The larger the transition phase, the smoother... starting as soon as possible will cause less pain for everybody... >From the cost point of view: + IPv6 should be seen as an evolution of current IP version 4. People that understand IP version 4 (network admins) should also learn easily IP version 6. Unfortunately IPv6 is often referred to as "a new technology", but in the end... it is not. It is (only?) the plain old IP, with some improvements... + On the "vendor front". IPv6 should be seen also as the natural evolution on IP technology. If any vendor wished to keep their share in the IP market, they should be able to support it, without any significant extra cost for customers. However... i dont really think the hardware factor is nowadays a serious problem for people currently building dual-stack networks (yes, in some parts of the world, people are doing it!!!) To conclude, nobody (i think) wishes to end IPv4 addresses anywhere in the years to follow...
