    It’s not terribly difficult to learn when you avoid trying to relate it to IPv4 concepts. Particularly: forget about LAN addresses and NAT, and instead think about a large block of public addresses being subdivided between local devices.

      instead think about a large block of public addresses being subdivided between local devices.

      Thinking about all my devices being exposed like that gives me the heebie jeebies. One public facing address hiding everything else on a private network is much less frightening to my monkey brain.

        This is what a firewall is for. Blocks inbound to the whole subnet space. Better than a NAT, which can open a port through STUN or simply a malformed packet.
