Internet Assigned Numbers Authority (IANA) Procedures for the Management
of the Service Name and Transport Protocol Port Number Registry
Abstract
This document defines the procedures that the Internet Assigned
Numbers Authority (IANA) uses when handling assignment and other
requests related to the Service Name and Transport Protocol Port
Number registry. It also discusses the rationale and principles
behind these procedures and how they facilitate the long-term
sustainability of the registry.
This document updates IANA's procedures by obsoleting the previous
UDP and TCP port assignment procedures defined in Sections 8 and 9.1
of the IANA Allocation Guidelines, and it updates the IANA service
name and port assignment procedures for UDP-Lite, the Datagram
Congestion Control Protocol (DCCP), and the Stream Control
Transmission Protocol (SCTP). It also updates the DNS SRV
specification to clarify what a service name is and how it is
registered.
