I have no idea what MySQL is doing. I'm just telling you that a default
inet6 wildcard socket on any BSD does *not* use mapped IPv4 and
therefore will *not* listen to IPv4. That is intentional and *not* a
bug. A program that really wants to use the same socket for both *must*
set ipv6only to 0 via the appropiate setsockopt call.
