::2/128 is not a valid ipv6 address. In IPv6 there is only one address for localhost, ::1. If you need other local addresses on lo1, either use the automatically added link-local address (fe80::1%lo1) or set a unique local address (https://en.wikipedia.org/wiki/Unique_local_address). $ doas ifconfig lo1 inet6 alias fd00::2/64 $ ping6 fd00::2 PING fd00::2 (fd00::2): 56 data bytes 64 bytes from fd00::2: icmp_seq=0 hlim=64 time=0.153 ms ^C /Benno > ^ this hangs > So does this: # ping6 ::2 > > ::1 works fine: > # ping6 ::1 > PING ::1 (::1): 56 data bytes > 64 bytes from ::1: icmp_seq=0 hlim=64 time=0.369 ms > 64 bytes from ::1: icmp_seq=4 hlim=64 time=0.340 ms > ^C > --- ::1 ping statistics --- > 2 packets transmitted, 2 packets received, 0.0% packet loss > round-trip min/avg/max/std-dev = 0.180/0.362/0.481/0.104 ms > > Here is /etc/hostname.lo1: > #inet 127.0.0.1 255.0.0.0 > inet 127.0.0.2 255.0.0.0 > inet alias 127.0.0.3 255.0.0.0 > > #inet6 ::1 128 > inet6 ::2 128 > inet6 alias ::3 128 > > pf.conf has nothing concerning lo1.
