    CGNAT is a nasty hack to work around the shortage of IPv4 addresses. It’s not used with IPv6.

    IPv6 should never be behind NAT which is a hack to extend the address space of Ipv4.

    It all is if you’re getting both. You’re sharing IPs with many different devices at the same time. That’s how it works.

    Read up on it.
