When assigning dynamic ports, the OS can use any ports available from the range of ports designated for this purpose.Ī port is identified by its port number. A dynamic port - also called a private port - is one that is assigned to a process or service at the time the port is needed, usually when the process or service is started. A static port is one whose association with a process or service does not change.
The ports can be either static or dynamic. Software-based ports are identified by 16-bit integers that range from 0 to 65535. The host computer uses these ports to direct traffic to the associated process or service. Software-based ports are numbered and can be assigned to specific processes or services. A software-based port - sometimes referred to as a virtual port - is a logical communication endpoint that's managed by the host's operating system ( OS). A hardware-based port is a physical interface - such as a jack or socket - for connecting with other systems. What are dynamic private ports?Ī port can be either hardware-based or software-based. The dynamic port numbers (also known as the private port numbers) are the port numbers that are available for use by any application to use in communicating with any other application, using the internet's Transmission Control Protocol ( TCP) or the User Datagram Protocol ( UDP).
