1.  Introduction

   The "Service Name and Transport Protocol Port Number Registry"
   [IANA-SERVICE] records several NETCONF-related port and service name
   assignments such as 830 for NETCONF over Secure Shell (SSH)
   [RFC6242], 831 for NETCONF over the Blocks Extensible Exchange
   Protocol (BEEP) [RFC4744], 832 for NETCONF over the Simple Object
   Access Protocol (SOAP) [RFC4743], 4334 for NETCONF Call Home
   [RFC8071], and 6513 for NETCONF over Transport Layer Security (TLS)
   [RFC7589][I-D.ietf-netconf-over-tls13].

   However, many of these assignments are for a transport protocol
   (i.e., UDP) for which the requesting application does not apply.

   It is understood that these assignments were made when the practice
   at that time (prior to 2011) was to automatically assign a port
   number for both TCP and UDP, even if a request was for only one of
   these transport protocols.

   Also, many of the assignments are for protocols that are not deployed
   and which were tagged as Historic: [RFC4743] and [RFC4744].
   [I-D.ietf-netconf-rfc4743-rfc4744-to-historic] reported in 2012 that
   these two protocols:

   |  "have shown very little (if any) implementations and deployment"

   This document de-assigns these port numbers, that fall in the System
   Ports range.

   Consistent with Section 8.2 of [RFC6335], this document does not de-
   assign service names; only port numbers (for specific transport
   protocols) are de-assigned for better usage of available scarce
   resources.

2.  Security Considerations

   Releasing back some port numbers softens the exhaustion risk of
   available port number space (especially the System Ports range).

   This document does not describe any protocol.

3.  IANA Considerations

   This document requests IANA to update the "Service Name and Transport
   Protocol Port Number Registry" registry [IANA-SERVICE] as specified
   in the following subsections.

      Note to the RFC Editor: Please replace "THIS_DOCUMENT" with the
      RFC number to be assigned to this document.
