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.
