An ephemeral port is a short-lived transport protocol port for Internet Protocol (IP) communications allocated automatically from a predefined range by the IP software. It is used by the Transmission Control Protocol (TCP), User Datagram Protocol (UDP), or the Stream Control Transmission Protocol (SCTP) 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.
