Synopsis: sockstat -4 does not show some listening IPv4 sockets State-Changed-From-To: open->closed State-Changed-By: ume State-Changed-When: Wed Jul 10 09:52:48 PDT 2002 State-Changed-Why: Because listening an IPv4 connection via an IPv4-mapped IPv6 address is NOT an IPv4 socket, it shouldn't be shown if you specify to show only an IPv4 socket. There are some disscussion about security weakness of an IPv4-mapped IPv6 address. Your confusion is an typical case. So, I think it is better to change to don't enable an IPv4-mapped IPv6 address by default. I'll change it for 5-CURRENT before 5.0-RELEASE is out. But, I have no plan for 4-STABLE to avoild POLA violation.
