I'm not sure I understand the issue, but setting IPV6_V6ONLY to 0 by default is not an option because asyncio wants to serve IPv4 and IPv6 with 2 distinct sockets on purpose. The reason for that is because when an IPv4 connection occurs we want getpeername/getsockname to return '127.0.0.1' instead of '::ffff:127.0.0.1'. Also, IPV6_V6ONLY = 1 is set by default on all platforms. It is not set on Windows because IPPROTO_IPV6 constant is missing due to issue29515, but that doesn't matter because IPV6_V6ONLY = 1 is already the default on Windows. As for Linux, /proc/sys/net/ipv6/bindv6only shouldn't matter because setting the option in Python is supposed to overwrite what /proc/sys/net/ipv6/bindv6only dictates. With that said, what's your use case exactly? Why does your test script uses AF_INET6 and an IPv4 address? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36208> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
