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, three of these assignments (831, 832, and 833) are for
   protocols that are not deployed and were tagged as Historic
   ([RFC4743] and [RFC4744]).  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.

2.  Operational Considerations
   There are no known implementations and deployments of protocols that
   rely upon the port numbers released back by this document.
   Existing configurations (if any) that associate the released port
   numbers with the service names "netconf-beep" and "netconfsoaphttp"
   need to be reassessed and updated according to the actions in
   Section 4.
   Other than that, there are no new operations or manageability
   requirements introduced by this document.
3.  Security Considerations
   This document does not describe any protocol.  As such, this document
   does not introduce any new security vulnerability.
4.  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.
   De-assigned allocations are marked per Section 8.2 of [RFC6335].
   These actions are not repeated here.
      Note to the RFC Editor: Please replace "THIS_DOCUMENT" with the
      RFC number to be assigned to this document.
