>From my perspective, doing both IPv6-only nat64 and IPv4 NAT44 is
required.  I see 2 types of customer and handset pairs:  those that
require IPv4 and those that can work well with IPv6.  For those that
require IPv4, NAT44 is the path.  We do it today for 99% of our 30
million customers

For users that can work well with IPv6, we MUST transition them to
IPv6 to start chipping away at the IPv4 only user base and demonstrate
to the community at large that IPv6 is REAL and NOW. We, as SPs, have
to gain experience in supplying IPv6 services and the only way to do
that is to start rolling it out to customers, one handset model at a
time.

In theory, there are a group of customers that require IPv4 and IPv6
at the same time, aka dual stack.  But, i think it is only in theory,
All the *real world use cases* i am aware of 100% work with IPv4-only
NAT44.  Some subset of that can work with IPv6-only + NAT64, and that
is the subset i will start to transition and grow.
