    In IPv6 you still need loopback addresses or something similar, but you
    only get one of them - ::1. You also get the massive link-local space of fe80::/10 on each interface including loopback.

    whatever the heck Gene's talking about.

    Historically we do not get very far here when talking about IPv6 with
    Gene.

    Thanks,
    Andy

    True Andy, but there's no ipv6 within 100 miles of me. This is rural WV,
    not enough people to need it.

    The Linux kernel comes with IPv6 on every interface (including
    loopback), unless you go out of your way to disable it. That is the
    topic of this sub-thread.

    Thanks,
    Andy
