ephemeral port numbers and well known port numbers
Ephemeral port numbers and well-known port numbers.
A well-known port is a fixed port number ranging from 0 to 1023, assigned by the Internet Assigned Numbers Authority (IANA) for specific services and protocols, such as HTTP (port 80) and FTP (port 21). In contrast, an ephemeral port is a temporary port number assigned dynamically by the operating system for short-lived communication sessions, typically ranging from 49152 to 65535. Well-known ports facilitate standardized communication, while ephemeral ports enable client applications to establish connections without requiring pre-defined port numbers.
Lasting for a very short time, short-lived; transitory: the ephemeral joys of childhood. It can mean "lasting one day". As in Ephemeral Flowers, they last one day. Or in computer terminology an ephemeral port is a transport protocol port for Internet Protocol communications where each client process is assigned a temporary port number for its use. When that process is complete the port is closed.
A non-ephemeral port, also known as a well-known or registered port, is a port number that is typically reserved for specific services and applications. These ports range from 0 to 1023 for well-known ports and from 1024 to 49151 for registered ports. Unlike ephemeral ports, which are temporary and assigned dynamically for client-side connections, non-ephemeral ports are usually static and associated with server applications, such as HTTP (port 80) or FTP (port 21). They facilitate consistent communication between clients and servers.
Ephemeral port
TCP port numbers, as well as UDP port numbers, are 2-byte numbers, therefore, the range is from 0 to 65535.
We must believe that bad times last ephemeral. Ephemeral means time that does not last for long.

That is correct. Ephemeral and evanescent are synonyms.

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.
