Port number bits

WebThe TCP protocol provides 16 bits for the port number, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2^16 - 1) or 65,535. This is true for TCP IPv4 and IPv6, as the same TCP header format is used irrespective of TCP version. On Linux, it is easy to check this: Transport-layer protocols, such as the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), transfer data using protocol data units (PDUs).
