    Try next DNS addr after all connect failures
    
    There are many more ways an IPv6 connection can fail than just
    CONNREFUSED and HOSTUNREACH. For example ETIMEDOUT, NETUNREACH
    and more. Try the next DNS addr after all connect() failures,
    no matter what the errno code, to ensure we always fallback
    to IPv4 eventually.
