What is the ephemeral port range according to IANA?

The correct choice identifies the ephemeral port range specified by the Internet Assigned Numbers Authority (IANA). Ephemeral ports are used by the operating system to assign temporary ports for client-side communication during a session with a server. This typically helps to establish a temporary channel for data transmission between devices.

According to IANA, the range for ephemeral ports is from 49152 to 65535. These ports are generally assigned dynamically and are used by a client program when establishing a connection to a server, allowing for multiple simultaneous connections without conflicts. This specific range is designated to avoid problems with reserved ports and prevents interference with well-known port assignments.

Understanding the ephemeral port range is crucial for network configurations, firewall settings, and troubleshooting connection issues. It helps in managing how clients communicate with servers and ensures that resources are managed effectively within networking environments.
