> IPv6 was released in 1998. ... Who was stopping anyone from doing it then, and who is stopping anyone from doing it now?
Well, for a long time, IPv6 didn't work very well. We're past that, mostly. Google reports that 45% of their incoming connections worldwide are IPv6.[1]
Growth rate has been close to linear, at 4%/year, since 2015. IPv6 should pass 50% some time in 2025.
Mobile is already 70%-90% IPv6. They need a lot of addresses.
Most of the delay comes from enterprise networks. They have limited connectivity to the outside world, and much of that limiting involves some kind of address translation. So a "corporate IPv6 strategy" is required.
