Reviewer: Brian Haberman Review result: Ready with Nits I just have a few comments/questions on this draft. Overall, it is in pretty good shape... 1. Section 2.2.3 looks like a complete re-production of RFC 5952, but I don't see a reference to 5952. Is the intent to deprecate 5952 since its content is now contained within 4291bis? 2. Section 2.6.1 captures some information about reserved IPv6 multicast addresses, but not all of them. I think it would be beneficial to point to the IPv6 Multicast Address Allocation registry maintained by IANA, much like the way Section 2.3 points to the IANA registries. 3. Also in Section 2.6.1, the names of reserved addresses, like "All Nodes Addresses", were made all lowercase. Was that intentional? Given that IANA refers to them with capitalization, it would seem that we need to be consistent. So, I would either retain the capitalization in this document or ensure that Section 3 directs IANA to update the names in the registries.
