Here's a thought.
Industry leading bodies* should announce that from 2026 all internet
connections sold in the UK will be IPv6 only, and thus all CPEs must
support IPv6 on the WAN and the LAN side, with no IPv4 on either. ISPs
can then offer a DNS64/NAT64 service for customers, particularly
consumers, who can't implement their own solution.
Here's a brief but interesting read with some real-world testing of
IPv6-mostly networks:
https://labs.ripe.net/author/ondrej_caletka_1/deploying-ipv6-mostly-access-networks/
It's encouraging that some OSes have built-in CLATs, and hence will
function with NAT64 even in the absence of DNS64. However, Windows and
Linux lag behind macOS and iOS/Android in this area.
There's also lots of legacy IoT around. Try telling a customer that
their home heating or lighting or security camera will no longer work on
your Internet service, because "we only do IPv6".
Therefore I think you're stuck with dual-stack on the LAN side for some
time yet, in conjunction with a CLAT on the CPE. I don't see that it
causes any harm though - and if over time it becomes less and less used,
then that's fine too.
The bigger problem I see is the complete unwillingness of the majority
of content providers to make their content accessible over v6, even
though in some cases it's only a few clicks for them to do it. They
*could* do it, but they don't.
A certain well-known broadcasting organization comes to mind - one which
has been regarded as a technical leader for the last 100 years.
Until that changes, CGN will continue to be heavily used (which is what
started this thread).
