the moment (behind NAT, presumably)? As a percentage of subscribers, what
does that equate to?
I know on quite a few none geek households that have multiple
nets today using double or triple NAT. These households
will be your multi-subnet IPv6 customers. The NAT boxes
will be replaced with ones that do DHCPv6 PD (both up and
down stream).
Handing out an IPv6 /56 to a DSL or cable customer should be handled much
the same way as giving them an IPv4 /29 is today -- ask, and it shall be
provided, but it's wasteful[1] to do so by default.
One won't hand out a /56. Think about how the above CPE
boxes will work with PD. You will get multiple /64 requests
from the border CPE box with different IAID on them, one
for each subnet in use. The border CPE box could also
consolidate the requests from downstream if it so desired
but I would expect that would not be the default configuration.
