Abstract

This specification defines an extension to the multicast addressing architecture of the IP Version 6 protocol. The extension presented in this document allows for unicast-prefix-based allocation of multicast addresses. By delegating multicast addresses at the same time as unicast prefixes, network operators will be able to identify their multicast addresses without needing to run an inter-domain allocation protocol.

1. Introduction

   This document specifies an extension to the multicast portion of the

   IPv6 addressing architecture [ADDRARCH].  The current architecture

   does not contain any built-in support for dynamic address allocation.

   This proposal introduces encoded information in the multicast address

   to allow for dynamic allocation of IPv6 multicast addresses and IPv6
