CGNAT ?!? Huh, I would have expected Starlink to be IPv6 only...
It’s either CGNAT or ponying up $60 per IPv4 address.
That's a staggering amount of money & it isn't locked up in assets like real estate.
This scarcity creates perverse incentives, I'm surprised that the governments aren't doing their job in first forcing new hardware to be IPv6-compatible, then later forbidding new hardware to be IPv4-compatible, like they did for digital TV tuners and low consumption light bulbs... maybe because the lobbying is pushing in the opposite direction in this case for the aforementioned reason ?
Only 28% of Alexa top 1000 sites support IPv6.
Very, very few, if any, consumers of commercial ISPs have only IPv6 access.
