we'll see dual-stack for at least a decade or two to come.
ISP's are very good at one thing, driving out unnecessary cost.
Running dual stack increases cost. While I'm not sure about the 5
year part, I'm sure ISP's will move to disable IPv4 support as soon
as the market will let them as a cost saving measure. Runing for
"decades" dual stacked does not make a lot of economic sense for
all involved.
So, can you elaborate why you think the cost of running dual stack is
higher than the cost of spending time&money on beind on the bleeding
edge to do v6-only yet supporting v4 for your existing and future
customers still wedded to the older IP protocol?
