Table of Contents

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. Also, many of the assignments are for protocols that are not deployed and 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 unused port numbers.¶

Consistent with Section 8.2 of [RFC6335], this document does not de-assign service names; only port numbers 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.¶
