Hi, Forrest:
1) I have a question:
If I subscribe to IPv6, can I contact another similar subscriber to
communicate (voice and data) directly between two homes in private like
the dial-up modem operations in the PSTN? If so, is it available
anywhere right now?

Let me start with I think we're largely on the same page here.
The transition I see happening next is that the consumer traffic
largely moves to IPv6 with no CG-NAT. That is, if you're at home or
on your phone watching video or doing social media or using whatever
app is all the rage it's going to be over IPv6.
My point was largely that I believe that at some point the big
consumer (not business) focused companies are going to realize they
can use market forces to encourage the remaining IPv4-only eyeball
networks to transition to support IPv6 connections from their
customers. I don't know if the timeframe is next year or 20 years
from now, but I do know the tech companies are very good at looking
at the costs of maintaining backwards compatibility with old tech and
figuring out ways to shed those costs when they no longer make sense.
If they can utilize various forms of pressure to make this happen
quicker, I fully expect them to do so.
Inside a business network, or even at home, it wouldn't surprise me
if we're both long gone before IPv4 is eradicated. I know there is
going to be a lot of IPv4 in my network for years to come just because
of product lifecycles.
As far as "CG-NAT-like" technologies go (meaning NAT in a provider's
network), they're unfortunately going to be with us for a long time
since customers seem to want to be able to reach everything regardless
of the IPv4 or IPv6 status of the customer or endpoint. I also
expect that most service providers with business customers are going
to be carrying both IPv4 and IPv6 for a long time, not to mention
doing a fair bit of translation in both directions.
I won't go deeply into the whole IPv4 vs IPv6 discussion for a
business customer's "public address" because the topic is far too
nuanced for an email to cover them accurately. Suffice it to say
that I don't disagree that business today largely wants IPv4, but some
seem to be becoming aware of what IPv6 can do and are looking to have
both options available to them, at least outside the firewall.

Ok you've triggered me on your point 2. I'll address the elephant
in the room.
IPv4 is never ever going away.
Right now consumer services are mostly (mobile, wireless,
landline, wide generalization) are IPv6 capable. Most consumer
applications are ipv6 capable, Google, Facebook, etc.There is
light at the very end of the tunnel that suggests that one day we
won't have to deploy CGNAT444 for our consumers to get to content,
we may only have to do NAT64 for them to get to the remaining Ipv4
Internet. We're still working hard on removing our reliance on
genuine ipv4 ranges to satisfy our customer needs, It's still a
long way off, but it's coming.
Here's the current problem. Enterprise doesn't need ipv6 or want
ipv6. You might be able to get away with giving CGNAT to your
consumers, but your enterprise customer will not accept this. How
will they terminate their remote users? How will they do B2B with
out inbound NAT? Yes, there are solutions, but if you don't need
to, why? They pay good money, why can't they have real ipv4? All
their internal networks are IPv4 rfc1918. They are happy with
NAT. Their application service providers are ipv4 only. Looking
at the services I access for work things like SAP, SerivceNow,
Office386, Sharepoint, Okta, Dayforce, Xero, and I'm sure many
more, none can not be accessed on ipv6 alone.. Their internal
network lifecycle is 10+ years. They have no interest in trying
new things or making new technology work without a solid financial
reason and there is none for them implementing ipv6. And guess
where all the IP addresses we're getting back from our consumers
are going? Straight to our good margin enterprise customers and
their application service providers. Consumer CGNAT isn't solving
problems, it's creating more.
The end of IPv4 isn't nigh, it's just privileged only.
PS When you solve that problem in 50 years time, I'll be one of
those old fogey's keeping an IPv4 service alive as an example of
"the old Internet" for those young whippersnappers to be amazed by.

Brett
