Which basically indicated that you don't understand.  There is flag
day.  There is no state change.  There is a addition of a parallel
service and eventually removal of a legacy service.

Additionally how do you account for Comcast enable IPv4+IPv6 for
their entire customer base (residential done, business in progress).

IPv4 only -> dual stack -> IPv6 only

Now "dual stack" includes but is not limited to:

a) IPv4 Native + IPv6 Native
b) IPv4 Native + IPv6 Tunneled    (6to4, 6in4, 6rd)
c) IPv4 CGN + IPv6 Tunneled       (6rd)
d) IPv4 CGN + IPv6 Native
e) IPv4 Tunneled + IPv6 Native    (DS-Lite - Being deployed by ISPs in Europe and Asia)
f) IPv4 Translated + IPv6 Native  (DNS64/NAT64,
			           464xlat - lots of mobile networks do this).

6to4 and 6in4 are deployable by individuals without the co-operation
of their ISP though ISPs can make these work better.
