Definitions for Ephemeral port
This page provides all possible meanings and translations of the word Ephemeral port
An ephemeral port is a short-lived transport protocol port for Internet Protocol communications allocated automatically from a predefined range by the TCP/IP software. It is used by the Transmission Control Protocol, User Datagram Protocol, or the Stream Control Transmission Protocol as the port assignment for the client end of a client–server communication to a well known port on a server. On servers, ephemeral ports may also be used as the port assignment on the server end of a communication. This is done to continue communications with a client that initially connected to one of the server's well-known service listening ports. File Transfer Protocol and Remote Procedure Call applications are two protocols that can behave in this manner. Note that the term "server" here includes workstations running services that receive connections initiatied from other clients. The allocations are temporary and only valid for the duration of the communication session. After completion of the communication session, the ports become available for reuse. Since the ports are used on a per request basis they are also called dynamic ports.151416
