The following address ranges are designated as private networks that should not be advertised: † 10.0.0.0 through 10.255.255.255 This RFC will be updated periodically, and in any case current information can be obtained from the Internet Assigned Numbers Authority (IANA). If you are developing a protocol or application that will require the use of a link, socket, port, protocol, etc., please contact the IANA to receive a number assignment.

Yes/No Port number may use the protocol conditionally only, or alternate its use (fallback if the other protocol fails). Port 22 Port number doesn't use the protocol, but may use the protocol on another specified port (e.g., port 22). N/A Not applicable or currently unassigned port number.

In order to maintain a level of standardization among the most commonly used ports, IANA (Internet Assigned Numbers Authority) has established that the ports numbered from 0 to 1024 are to be used for common services. The remaining ports up through 65535 are used for dynamic allocations or particular services. One of the many fundamental things to know as a network engineer is the function and port number used by a number of common services as well as many that are typically implemented during the course of a network engineer’s career.
