Abstract
The purpose of this document is to define IPv6 Multicast Id ranges that will not allow overlap between dynamically assigned global scoped addresses and dynamically assigned non-global scoped addresses, specifically dynamically assigned link-local scoped addresses. [RFC3307] defines IPv6 Multicast Group ID ranges for the following Permanent Addresses, Permanent Identifiers and Dynamic Addresses. However, there are certain multicast addresses that need to be assigned for closed systems that should not collide with the Group IDs used within the Internet. This document further defines the Dynamic Addresses into two ranges Dynamically Assigned Global (DAG) addresses and Dynamically Assigned Non-Global (DANG) addresses. The DANG range is further broken down to Dynamically Assigned Link-Local (DALL) addresses and the rest reserved for future. Future uses might be for Site-Local Scoped and Organization Scoped ranges. The DALL range may be used to simplify the design of MLD Snooping layer 2 switches. [RFC3171] defines the Local Network Control Block address range for IPv4. A similar range should be defined to possibly simplify the design of MLD Snooping layer 2 switches.
