Consider creating a listener socket from a hostname that resolves to
multiple addresses. It might be the case that the hostname resolves to
both an IPv4 and IPv6 address because it is reachable over both
protocols, but the IPv6 connectivity is provided off-host. In such a
case no local NIC will have IPv6 and so bind() would fail with the
EADDRNOTAVAIL errno. Thus it should be treated as non-fatal as long as
at least one socket was succesfully bound.
