Technical Summary Good, up-to-date documentation of IP multicast is close to non- existent. Particularly, this is an issue with multicast address allocations (to networks and sites) and assignments (to hosts and applications). This problem is stressed by the fact that there exists confusing or misleading documentation on the subject [RFC2908]. The consequence is that those who wish to learn about IP multicast and how the addressing works do not get a clear view of the current situation. The aim of this document is to provide a brief overview of multicast addressing and allocation techniques. The term 'addressing architecture' refers to the set of addressing mechanisms and methods in an informal manner. It is important to note that Source-specific Multicast (SSM) [RFC4607] does not have these addressing problems because SSM group addresses have only local significance; hence, this document focuses on the Any Source Multicast (ASM) model. This memo obsoletes and re-classifies to Historic RFC 2908, and re- classifies to Historic RFCs 2776 and 2909. Working Group Summary WG consensus appears sound and no major controversies were noted. Document Quality The document has undergone thorough review within IETF's Multicast community. This document was previously submitted for publication several years ago, but changes were suggested during AD review. The suggested changes have been made. Personnel Lenny Giuliano is the Document Shepherd. Ron Bonica is the Responsible Area Director.
