WebFor IPv4 addresses, two special forms are accepted instead of a host address: '' represents INADDR_ANY, which is used to bind to all interfaces, and the string '' represents INADDR_BROADCAST. This behavior is not compatible with IPv6, therefore, you may want to avoid these if you intend to support IPv6 with your Python programs. Webshould be copied from the in6addr_anyvariable which has in6_addrtype. In static initializations, IN6ADDR_ANY_INIT may also be used, which expands to a constant expression. Both of them are in network byte order. The IPv6 loopback address (::1) is available in the global in6addr_loopbackvariable. For initializations,
