Shepherd writeup

As required by RFC 4858, this is the current template for the Document 
Shepherd Write-Up. Changes are expected over time. 

This version is dated 1 November 2019. 

(1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header? 
Proposed Standard - this document requests that the status of '" be recorded in the Special-Use Domain Names registry as a name with special properties.

(2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections: 

Technical Summary 

   The specification for how a client discovers its local network's
   NAT64 prefix [RFC7050] defines the special name '' for
   this purpose, but in its Domain Name Reservation Considerations
   section that specification indicates that the name actually has no
   particularly special properties would require special handling, and
   does not request IANA to record the name in the Special-Use Domain
   Names registry.

   Consequently, despite the well articulated special purpose of the
   name, '' was not recorded in the Special-Use Domain
   Names registry as a name with special properties.

   This document describes the special treatment required, formally
   declares the special properties of the name, and adds similar
   declarations for the corresponding reverse mapping names.
