They are used by system processes that provide widely used types of network services. The port numbers in the range from 0 to 1023 are the well-known ports or system ports. Multiple applications are known to use this port. Port is not registered with IANA for the application Port is registered with IANA for the application
However, many unofficial uses of both well-known and registered port numbers occur in practice. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. Stream Control Transmission Protocol (SCTP) and Datagram Congestion Control Protocol (DCCP) also use port numbers. The even-numbered ports were not used, and this resulted in some even numbers in the well-known port number range being unassigned. Later, Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) needed only one port for bidirectional traffic (full duplex). Originally, port numbers were used by the Network Control Program (NCP) which needed two ports for half duplex transmission. This is a list of Internet socket port numbers used by protocols of Transport Layer of the Internet Protocol Suite for the establishment of host-to-host connectivity.
