It has started to fade away.  If you have IPv6 at home, statistically,
most of your traffic will be IPv6.  There will be outlier homes but
in general IPv6 will carry more traffic than IPv4.

B2B traffic isn't quite as high but there too IPv6 takes a significant
amount of traffic.

I've had to get new telephone numbers to fit in more customers over
the years with support for the old number being removed after a
year or so.

	462910 -> 4162910 -> 94162910

As for new telephones, yes this has been manditory, switching from
rotary to DTMF.  There was a period of overlap but support for
rotary phones was turned off in the exchange.

Most of you have thrown out several generations of computing devices
that have supported IPv6 without even being aware you were doing
so.  IPv6 support is 20+ years old.  My daughter, who has now left
home, has lived her entire life with equipement in the house that
has supported IPv6.  The house had working IPv6 connectivity before
she went to primary school.  She graduatuted from Y12 last year.

I'm still waiting for my ISP to turn on IPv6.  The CPE router
supports it.  I just routed around them to get IPv6 at home.

If you have a piece of computing equipement bought in the last 10
years that doesn't suppport IPv6 today it is because the manufacture
is a ludite, not because IPv6 doesn't work.
