An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...

At the same time, it is a feature-rich network debugging and investigation tool, since it can produce almost any kind of connection its user could need and has a number of built-in capabilities.
Unraid utilizes Docker to allow users to create and manage Docker containers to host applications on the system. In doing so, this allows Unraid users to host applications that may not support the Unraid operating system directly, could be difficult to install & remove, or may not behave correctly with other applications running on the same system.
curl defaults to displaying the output it retrieves to the standard output specified on the system (usually the terminal window). So running the command above, on most systems, displays the HTML contents of www.example.com in plain text on the active terminal window. The -o flag can be used to store the output in a file instead:
