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