   This document describes what it means to say that a DNS name is

   and the procedure for doing so.

The IESG plans to make a decision in the next few weeks, and solicits

The intended status of draft-cheshire-dnsext-special-names-01 is Standards Track. BCP would have been a better fit is the aim of this draft is to create a registry and a procedure for reserved DNS names.

In Section 1:

  'For example, IPv4 addresses 224.0.0.0 to 239.255.255.255 are
   multicast addresses [RFC2606], with 224.0.0.1 being the "all hosts"'

I suggest dropping that reference as example refers to IPv4 addresses discussed in RFC 5735; RFC 2606 is about Reserved Top Level DNS Names.

From Section 2:

  "Similarly, if a domain name has special properties that affect the
   way hardware and software implementations handle the name, which
   apply universally regardless of what network the implementation may
   be connected to, then that may be a candidate for having the IETF
   declare the name to be a Special-Use Domain Name and specify what
   special treatment implementations should give to that name."

That sounds like a good argument for the IETF declare a domain name as "Special Use". Does ".local" qualify for registration (draft-cheshire-dnsext-multicastdns-13)?

Are domain names as defined under this proposal to be considered as Internet protocol parameters?

From Section 3:

  "If it is determined that special handling of a name is required in
   order to implement some desired new functionality, then an IETF
   "Standards Action" RFC [RFC5226] needs to be published describing the
   new functionality ..."

In other words, if an author can get a Proposed Standard through the IETF process, he or she can get a registration for a Special-Use Domain Name.

In Section 7:

  'How should DNS Registrars treat requests to register this reserved
   domain name? Should such requests be denied? Should such requests
   be allowed, but only to a specially-designated entity? (For
   example, the name "www.example.org" is reserved for documentation
   examples and is not available for registration; however, the name
   is in fact registered; and there is even a web site at that name,
   which states circularly that the name is reserved for use in
   documentation and cannot be registered!)'

That would be:

   Domain Name: EXAMPLE.COM
   Registrar: RESERVED-INTERNET ASSIGNED NUMBERS AUTHORITY
   Whois Server: whois.iana.org
   Referral URL: http://res-dom.iana.org
   Name Server: A.IANA-SERVERS.NET
   Name Server: B.IANA-SERVERS.NET
   Status: clientDeleteProhibited
   Status: clientTransferProhibited
   Status: clientUpdateProhibited
   Updated Date: 26-mar-2004
   Creation Date: 14-aug-1995
   Expiration Date: 13-aug-2011

By the way, res-dom.iana.org is not responding on port 80.

In the IANA Considerations Section, draft-cheshire-dnsext-special-names creates a registry of Special-Use Domain Names. It is customary to populate a new registry with legacy entries such as the domain names mentioned in RFC 2606.
