Why you use well known ports?

It is a kind of standard. If both sides agree to use (for example) port 80 for HTTP (Web access), no special configuration, or specification of port number, is necessary. If non-standard ports are used, the client and the server have to agree on the port used. For example, if the server decides to use port 10080 for HTTP, the client has to know that this is the port to be used - and the user needs additional effort to acces that port, for example, by specifying the following address in the browser: http://www.sampleserver.com:10080

Ports in the range of 1024 to 49151 are known as?

Ports in the range of 1024 to 49151 are known as "registered ports." These ports are assigned by the Internet Assigned Numbers Authority (IANA) for specific services and applications, allowing organizations to use them for their software without conflicting with well-known ports (0-1023). While registered ports are not as tightly controlled as well-known ports, they are still recommended for use by specific applications to ensure proper functioning and to avoid port conflicts.

What is a non ephemeral port?

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.


What type of port number is assigned by IANA to commonly used services and applications?

What range of ports can either be used by TCP to identify the requested service on the destination device or as a client source port?

TCP ports can range from 0 to 65535. The well-known ports, which range from 0 to 1023, are typically reserved for specific services (e.g., HTTP uses port 80, HTTPS uses port 443). Ports ranging from 1024 to 49151 are known as registered ports and can be used by user applications. Ports from 49152 to 65535 are dynamic or private ports and are usually assigned temporarily for client source ports during communication.
