Good FOSS software and reliable service providers? Etc.
IPv6 doesn’t help anything if you’re behind CGNAT, you can have internal-only IPv6. There are good reasons to not have every household directly accessible to the outside world, so I’m sympathetic to that, but they also seem to love charging extra for it.
CGNAT only applies to IPv4. You cannot NAT IPv6 effectively. It’s not designed to be NATed. While there IS provisions for private IPv6 addressing, nobody actually does it because it’s pointless.
Sure, but NPTv6 exists, and I wouldn’t put it past an ISP to do something like that.
Network Prefix Translation isn’t the same thing. That’s used for things like MultiWAN so that your IPv6 subnet from another WAN during a failover event can still communicate by chopping off the first half and replacing the subnet with the one from the secondary WAN. It is not NAT like in IPv4 and doesn’t have all of the pitfalls and gotchas. You still have direct communications without the need for things like port forwarding or 1:1 NAT translations.
I’m a Network Engineer of over a decade and a half. I live and breath this shit. Lol.
