John, I think Scott and SM have addresses your queries quite exhaustively. We’ll still need IPv4 for quite some time.<BR>
<BR>
The policy has been approved in some RIR’s as-is and approved in other regions with a few changes. In line with the global PDP, for a policy proposal to pass as a global policy, it must get consensus (as-is) from all the 5 RIR’s. This is not the case with this policy and as Scott rightly puts it, we should be seeing a revised policy proposal soon.<BR>
<BR>

Adding to what Scott said, this is not like the transition between <BR>
ARPANET and the Internet which took over five years. Some people <BR>
have suggested not to extend the lifetime of IPv4 by adopting such <BR>
policies. Unfortunately, given the scale of the Internet, there will <BR>
still be a need for IPv4 for the years to come. There may be IPv4 <BR>
and IPv6 islands. You'll need gateways (dual-stack hosts) to connect <BR>
them together. It's not so difficult, relatively speaking, for web <BR>
access. Google, for example, already offers IPv6 access for some <BR>
networks. There are a lot of other "application" protocols in use <BR>
over the Internet. The translation gateways to get them to work <BR>
probably won't be on the ISP side as there is less demand.<BR>
<BR>
Take a look at your network and find out how many of your devices <BR>
support IPv6. Find out how many of the software you use have IPv6 support.<BR>
<BR>
