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
<ftp://venera.isi.edu/in-notes/iana/assignments/multicast-addresses>.
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 [RFC2119].

2. Fixed Scope Multicast Addresses

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

2.1 Node-Local Scope

FF01:0:0:0:0:0:0:1 All Nodes Address [ADDARCH]
FF01:0:0:0:0:0:0:2 All Routers Address [ADDARCH]

2.2 Link-Local Scope

FF02:0:0:0:0:0:0:1 All Nodes Address [ADDARCH]
FF02:0:0:0:0:0:0:2 All Routers Address [ADDARCH]

FF05:0:0:0:0:0:1:4 All-dhcp-relays [Bound,Perkins]
FF05:0:0:0:0:0:1:1000 Service Location [RFC2165]
-FF05:0:0:0:0:0:1:13FF

3.0 All Scope Multicast Addresses

These permanently assigned multicast addresses are valid over all
scope ranges. This is shown by an "X" in the scope field of the
address that means any legal scope value.

Note that, as defined in [ADDARCH], IPv6 multicast addresses which
are only different in scope represent different groups. Nodes must
join each group individually.

The IPv6 multicast addresses with variable scope are as follows:
