WebIn order to listen for UDP datagrams it is necessary to choose a port number and, optionally, a local IP address on which to listen. The combination of these two values is treated as a single entity called the socket address, which is represented by a struct sockaddr_in for IPv4 or a struct sockaddr_in6 for IPv6.
