Abstract

   This document reserves a string (ALT) to be used as a TLD label in
   non-DNS contexts.  It also provides advice and guidance to developers
   developing alternative namespaces.

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 reserves the label "ALT" (short
   for "Alternative") 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 should not be resolved
   using the DNS protocol.

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].
