WebEach socket has a crspding socket address that consists of an Internet addr and a 16-bit integer port, and is denoted by address:port. The port in the client's socket addr is assigned auto by the kernel when the client makes a connection request, and is known as an ephemeral port. Websin_port contains the port in network byte order. The port numbers below 1024 are called privileged ports (or sometimes: reserved ports).
