We are seriously behind other parts of the world.  It took Comcast
years to upgrade all of the equipement just to do the residential
side.  They are still doing the commercial side.  Optus handed me
a DOCSIS 2.0 modem, with serious buffer bloat issues, in the last
year to replace the broken +10 year old DOCSIS 1.0 modem I had.  I
have been asking Optus for IPv6 support since 2003.  At this rate
it will be 2024 before the modem needs to be replaced for hardware
reasons.

Now some DOCSIS 2.0 modems have IPv6 capable firmware releases but
most don't.

Free supplied all their customers 6rd (RFC5569 which was later
standardised with minor changes to improve address utilisation
efficiency and autoconfiguratib in RFC5969) capable modems back in
2008/2009 timeframe.  Comcast also used 6rd to deliver IPv6 for a
while.

Meanwhile I do have a IPv6 capable Netgear router with nothing for
it to talk to directly on the IPv6 side as the old router needed
to be replaced.  6to4 goes via a HE relay in Japan after crossing
the Pacific twice to get there.  Netgear doesn't offer a way to
configure 6in4 even though the box is capable of doing it if you
telnet in a run the configuration commands by hand.  These need to
be re-done each the the router reboots.

That said I as a customer should not have to resort to these measures
to get IPv6 going.  IPv6 should just be there by now.
