I believe most home ISP doesn't support IPv6 in many countries like Canada. Thus, resulting in IPv4 still being considered as "default".

Also, with the increasing numbers of devices connected everyday, we're running out of IPv4. Think of the demand vs supply curve (demand high, supply low, result = higher price/ip)

You can check IPv6 adoption in each country here: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...

Most is incorrect. Many big ISPs support IPv6. The IPv6 charts notice more IPv4 when people are working, and IPv6 while people at home (nights and weekends) because so many ISPs do support IPv6 and it just works. The big cable ISPs and the big cell phone (not sure if all, but some at least) support IPv6 to everyone and have been doing it for a long time because it just works (they had to do some effort early to get it to work).

The cellular carriers are now doing CGNAT for IPv4, so supporting IPv6 means less traffic has to run through their CGNAT gear.

I have noticed that when looking at the internal IPv4 address of my phone. What's the technical difference between Carrier Grade NAT and "traditional" NAT?

From what I can tell it is just the power. Traditional/home NAT runs on low powered computers. CNAT is the same thing, but with very powerful computers with a lot of memory so they can handle thousands of users (possibly each with gigabit internet connections!) behind one IP address.

The graph of IPv6 adoption over time on that page [1] is pretty cool because you can see the average jump up with COVID. I'd assume that means residential internet is more likely to use IPv6 over cell or work internet.

It also seems, that Starlink will not support IPv6 initially. At least the website and SpaceXs website are IPv4 only if that is a hint.

Correct, Starlink does not currently support IPv6.

Comcast/xfinity uses ipv6 and ipv4 for my connection.
