In it Postel first proposed a registry of assignments of port numbers to network services, calling himself the czar of socket numbers. [24] The first reference to the name "IANA" in the RFC series is in RFC 1083, published in December 1988 by Postel at USC-ISI, referring to Joyce K. Reynolds as the IANA contact.
A registered port is a network port designated for use with a certain protocol or application.. Registered port numbers are currently assigned by the Internet Assigned Numbers Authority (IANA) and were assigned by Internet Corporation for Assigned Names and Numbers (ICANN) before March 21, 2001, [1] and were assigned by the Information Sciences Institute (USC/ISI) before 1998.
Xerox Network Systems (XNS) Mail. Despite this port being assigned by IANA, the service is meant to work on SPP (ancestor of IPX/SPX), instead of TCP/IP. [36] 61: Reserved: Historically assigned to the NIFTP-Based Mail protocol, [38] but was never documented in the related IEN. [39] The port number entry was removed from IANA's registry on 2017 ...

The Internet Corporation for Assigned Names and Numbers (ICANN / ˈ aɪ k æ n / EYE-kan) is a global multistakeholder group and nonprofit organization headquartered in the United States responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the ...
URI schemes registered with the IANA, both provisional and fully approved, are listed in its registry for Uniform Resource Identifier (URI) Schemes. These include well known ones like: file - File URI scheme; ftp – File Transfer Protocol; http – Hypertext Transfer Protocol; https – Hypertext Transfer Protocol Secure
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
The assignment was issued by IANA on 17 March 2014, and is listed in the official IANA resource registry. There are a very limited number of port numbers, which are assigned by IANA for protocols recognized as viable, complying with current protocol design standards, and not already covered by existing Internet standards.
An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.
