                Reassignment of System Ports to the IESG
                    draft-kuehlewind-system-ports-05

Abstract

   In the IANA Service Name and Transport Protocol Port Number Registry,
   a large number of System Ports are currently assigned to individuals
   or companies who have registered the port for the use with a certain
   protocol before RFC6335 was published.  For some of these ports, RFCs
   exist that describe the respective protocol; for others, RFCs are
   under development that define, re-define, or assign the protocol used
   for the respective port, such as in case of so-far unused UDP ports
   that have been registered together with the respective TCP port.  In
   these cases the IESG has the change control about the protocol used
   on the port (as described in the corresponding RFC) but change
   control for the port allocation iis designated to others.  Under
   existing operational procedures, this means the original assignee
   needs to be involved in chnage to the port assignment.  As it is not
   always possible to get in touch with the original assignee,
   particularly because of out-dated contact information, this current
   practice of handling historical allocation of System Ports does not
   scale well on a case-by-case basis.  To address this, this document
   instructs IANA to perform actions with the goal to reassign System
   Ports to the IESG that were assigned to individuals prior to the
   publication of RFC6335, where appropriate.

1.  Introduction

   RFC 6335 [RFC6335] requires System Ports, also known as the Well
   Known Ports, in the range from 0 to 1023, to be assigned by the "IETF
   Review" or "IESG Approval" procedures [RFC8126].  For assignments
   done through RFCs published via the "IETF Document Stream" [RFC4844],
   the Assignee will be the IESG with the IETF Chair as the Contact.

   However, ports that were assigned before the publication of RFC 6335,
   are often assigned to individuals, even if they are part of the
   System Port range and have a corresponding RFC.  Besides the fact
   that System Ports are widely used by IETF protocols where the
   protocol specification is under IETF change control as defined in an
   RFC but the port itself may not, this situation is especially
   problematic if the assignment gets or needs to be changed.  The
   Assignee can change the assignment without confirmation of the IETF.
   However, if the IETF process requires a change, including de-
   assignment, this cannot be done without the agreement of the original
   Assignee.  Furthermore, no procedure is defined to change the
   assignment in cases where the original Assignee is not reachable or
   not available anymore.

   This document mainly aims to clarify the change control for protocols
   that are maintained by the IETF; it further also intends an update of
   currently unused or not maintained ports.  For this purpose this
   document instructs IANA to perform accumulative actions with the goal
   to re-assign currently assigned System Ports in the range from 0 to
   1023 to the IESG, where appropriate, which will also help to align
   existing entries in the "Service Name and Transport Protocol Port
   Number Registry" with the current procedures defined in RFC 6335.

2.  IANA Considerations

   IANA [will perform/has performed] actions with the goal to re-assign
   System Ports in the port range from 0 to 1023 that are currently
   assigned in the "Service Name and Transport Protocol Port Number
   Registry" (https://www.iana.org/assignments/service-names-port-
   numbers/service-names-port-numbers.xhtml) to clarify the IESG's
   responisibility in managing those allocations.  When the re-
   assignment is performd, the contact data for these assignments should
   be adjusted to refelct the IESG <iesg@ietf.org> as assignee and the
   IETF Chair <chair@ietf.org> as point of contact.  The original
   assignee and respective contact information should be preserved as a
   note against the revised assignment data.

   To perform the re-assignment, IANA is requested to contact the
   current Assignees by email with the registered email address to
   request the transfer.  If the provided email address is not valid
   anymore, IANA is requested to report this to the IESG, and the IESG
   is requested to perform actions, such as sending requests to the
   ietf@ietf.org mailing list to determine updated contact information.
   If these actions do not show success within 4 weeks, the IESG is
   requested to make a decision about the re-assignment of the port in
   question.

   If the current assignee does not agree to the re-assignment or does
   not reply within four weeks, IANA is requested to inform the IESG
   which then is requested to make a decision about the re-assignment of
   the port in question.

   Before the start of this re-assignment process, IANA [will also
   update/has further updated] the Reference column with the following
   reference for the listed ports that have a corresponding published
   RFC that uses this port number, as well as the Assignment Notes
   column for historic RFCs:

3.  Security Considerations

   This draft instructs IANA to perform actions on the Service Name and
   Transport Protocol Port Number Registry.  It does not change the use
   of the ports or protocols running on them.  Therefore the security of
   these protocols is not impacted by these changes to the registry.
