In all fairness, upgrading the legacy last-mile e.g. DSL infrastructure to =
support native IPv6 may be too expensive to make any economic sense.
Note that Vz FiOS users are not affected by this. And noting that Vz has ~5=
.5M FiOS HSI customers and ~3M DSL customers (per the last earning report),=
and noting that DSL network is not getting any new investment (in fact, cu=
stomers are being moved from DSL to FiOS), the CGN usage for DSL customers =
isn't quite surprising.

Many ISPs around the world are choosing to not to invest in the DSL network=
the way they used to.

To "opt out" of CGN sign onto your My Verizon account and select "Opt out o=

I like how, according to the document, Verizon must first break your
connectivity, prior to you being able to opt-out. :-)
Also:
select "Opt out of Carrier Grade Network"
Smart wording. :-)
Frankly, I'm surprised to see this news. I thought Verizon had better
things to do that plan any kind of upgrades or changes to something
that everyone thought they consider dead anyways.
