Description Michael Osipov 2021-03-27 20:41:49 UTC 
Here is the output:
> $ sockstat -6
> USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
> mosipov  socat      61935 5  tcp6   ::1:20000             *:*
> redis    redis-serv 1031  7  tcp6   *:6379                *:*
> root     sshd       1016  3  tcp6   *:22                  *:*

> ntpd     ntpd       944   26 udp6   fe80::1%lo0:123       *:*

while I would expect to see:
> $ sockstat -6
> USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
> mosipov  socat      61935 5  tcp6   [::1]:20000           *:*
> redis    redis-serv 1031  7  tcp6   *:6379                *:*
> root     sshd       1016  3  tcp6   *:22                  *:*
> ntpd     ntpd       944   20 udp6   *:123                 *:*
> ntpd     ntpd       944   22 udp6   [fe80::yyy:9466%em0]:123 *:*
> ntpd     ntpd       944   24 udp6   [2003:xxx:yyy:9466]:123 *:*
> ntpd     ntpd       944   25 udp6   [::1:]123             *:*
> ntpd     ntpd       944   26 udp6   [fe80::1%lo0]:123     *:*

As most software outputs inet6 socket address string representation to avoid confusion.
