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][NETCONF-over-TLS].

However, three of these assignments (831, 832, and 833) are for protocols that are not deployed, and the relevant RFCs ([RFC4743] and [RFC4744]) have been marked Historic. All these assignments are thus no longer required to support these services.

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.
