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. WebAug 18, 2024 · If the socket is not connected, the getsockname function can be used to determine the local port number associated with the socket but the IP address returned is set to the wildcard address for the given protocol (for example, INADDR_ANY or "0.0.0.0" for IPv4 and IN6ADDR_ANY_INIT or "::" for IPv6).

WebIn the simulator, INADDR_ANYhas the following semantics: When receiving, a socket bound to this address receives packets from allinterfaces.
