Dynamic or private ports are port numbers in the range of 49152 to 65535, as defined by the Internet Assigned Numbers Authority (IANA). These ports are typically assigned dynamically by the operating system for client-side applications when establishing connections to servers, allowing multiple applications to use the same port number without conflict. They are not officially assigned to any specific service, making them suitable for ephemeral use in various network communications.

When that process is complete the port is closed.
