1.0 Introduction

   This document defines the initial assignment of IPv6 multicast
   addresses.  It is based on the "IP Version 6 Addressing Architecture"
   [ADDARCH] and current IPv4 multicast address assignment found in
   .
   It adapts the IPv4 assignments that are relevant to IPv6 assignments.
   IPv4 assignments that were not relevant were not converted into IPv6
   assignments.  Comments are solicited on this conversion.

   All other IPv6 multicast addresses are reserved.

   Sections 2 and 3 specify reserved and preassigned IPv6 multicast
   addresses.

   [ADDRARCH] defines rules for assigning new IPv6 multicast addresses.

   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 [RFC 2119].

2. Fixed Scope Multicast Addresses

   These permanently assigned multicast addresses are valid over a
   specified scope value.
