Comment on ISP put me behind NAT

  This is a myth. There are large swath of IPv4 address spaces totally unused and many ISPs hoard them without actually using them.

  An IPv6 only internet connection would also still be miles better than CGNAT connection.

    How? You can literally turn IPv4 off on your whole network, or selectively by device. But if you turn off your IPv4 you will get cut off of a good chunk of the internet.

      There is nothing wrong with an organization sharing an single IPv4 internally via NAT, but if your ISP sells you a connection to the internet, this by definition means you get a unique public IP address, otherwise it isn’t an internet connection.

      IPv6 support could be better for sure, but it is still much better than not having an internet connection at all as in the case of a CGNAT.

        No it doesn’t. It means you have access to the internet through that company’s infrastructure. You still have full access to the internet behind a CGNAT even if you can’t be reached directly from the internet.

        CGNAT usually only applies to the IPv4. The IPv6 prefix you get is usually public.
