Reassignment of System Ports to the IESG
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.

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
