Special IPv6 addresses - IBM

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. WebYou can use setsockopt () to set the SO_REUSEADDR socket option, which explicitly allows a process to bind to a port which remains in TIME_WAIT (it still only allows a single process to be bound to that port). This is the both the simplest and the most effective option for reducing the "address already in use" error. the point a is at –2 and the point b is at 7WebThe application has not issued a specific bind for this socket, even to the INADDR_ANY or in6addr_any IP address. The address specified on the TCPSTACKSOURCEVIPA parameter is a static VIPA or active dynamic VIPA. If these conditions are met and this is an IPv4 packet, TCP/IP uses the address specified on the TCPSTACKSOURCEVIPA parameter. sideways view on computer
