D.1 Well-known port numbers
Ports are used in protocols such as TCP and UDP to identify the end points of logical connections that carry long-term conversations. For many applications it is useful to have the service port predefined, so that clients connecting to a server know what port to connect to for widely used applications such as FTP, Telnet, DNS, and so on. These ports are sometimes called well-known ports or assigned ports. These ports are controlled and assigned by the IANA, and on most systems can be used only by system (or root) processes or by programs executed by privileged users. The assigned ports take only a small part of the available port space, for many years restricted to the range 0–255. Recently, the range has been expanded by the IANA to 0–1,023.
