                  The ALT Special Use Top Level Domain
                      draft-ietf-dnsop-alt-tld-05

Abstract

   This document reserves a string (ALT) to be used as a TLD label in
   non-DNS contexts or for names that have no meaning in a global
   context.  It also provides advice and guidance to developers
   developing alternate namespaces.

   [ Ed note: This document lives in GitHub at:
   https://github.com/wkumari/draft-wkumari-dnsop-alt-tld . Issues and
   pull requests happily accepted. ]

   [ Question for Working Group.  It has been proposed that the string
   .ALT should be replaced with something else e.g. .NOT-DNS.  As naming
   discussions in the IETF are always short, simple, and not
   controversial, we figured we should open these for discussion now.
   We would appreciate clear feedback on preference and rationale. ]

1.  Introduction

   Many protocols and systems need to name entities.  Names that look
   like DNS names (a series of labels separated with dots) have become
   common, even in systems that are not part of the global DNS
   administered by IANA.

   This document provides a solution that may, in many cases, be more
   appropriate than [RFC6761].

   This document reserves the label "ALT" (short for "Alternate") as a
   Special Use Domain ([RFC6761]).  This label is intended to be used as
   the final (rightmost) label to signify that the name is not rooted in
   the DNS, and that normal registration and lookup rules do not apply.

1.1.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

1.2.  Terminology

   This document assumes familiarity with DNS terms and concepts.
   Please see [RFC1034] for background and concepts, and
   [I-D.ietf-dnsop-dns-terminology] for terminology.
