TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses, [ 1 ] However, many unofficial uses of both well-known and registered port ...
Ports with numbers 0–1023 are called system or well-known ports; ports with numbers 1024-49151 are called user or registered ports, and ports with numbers 49152-65535 are called dynamic, private or ephemeral ports. [2] Both system and user ports are used by transport protocols (TCP, UDP, DCCP, SCTP) to identify an application or service.
This includes the registration of commonly used TCP and UDP port numbers for well-known internet services. The port numbers are divided into three ranges: the well-known ports, the registered ports, and the dynamic or private ports. The well-known ports (also known as system ports) are those numbered from 0 through 1023. The requirements for ...
Port numbers are categorized into three basic categories: well-known, registered, and dynamic or private. The well-known ports are assigned by the Internet Assigned Numbers Authority (IANA) and are typically used by system-level processes. Well-known applications running as servers and passively listening for connections typically use these ports.
At the server end of the communication session, ephemeral ports may also be used for continuation of communications with a client that initially connected to one of the services listening with a well-known port. For example, the Trivial File Transfer Protocol (TFTP) [1] and Remote Procedure Call (RPC) applications can behave in this manner.

The Internet Assigned Numbers Authority (IANA) has divided port numbers into three ranges. [6] Port numbers 0 through 1023 are used for common, well-known services. On Unix-like operating systems, using one of these ports requires superuser operating permission. Port numbers 1024 through 49151 are the registered ports used for IANA-registered ...
Shedeur Sanders on being tight with Cam Ward: "It's cool that we're close because if we weren't the media try to pin us against each other." If he doesn't go #1 would he hold a grudge?
