Assigned numbers
<standard> The
RFC STD 2 documenting the currently assigned values from several series of numbers used in network
protocol implementations.
This RFC is 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., you should contact the IANA to receive a number assignment.
