It's even more confusing: The Linux kernel (and only the Linux kernel)
has a feature that "bind on all interfaces" takes both of IPv4 and IPv6
interfaces/ip addresses. This is controlled via the the
"net.ipv6.bindv6only" sysctl.
Per default this is usually activated (which is IMHO a bad decision
because I wouldn't expect that) - at least on Debian/Sarge IIRC.
