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.
