Abstract:

   This document defines the problem space and associated requirements
   for automatically assigning multicast addresses in zero-configuration
   ("zeroconf") networking environments.  It addresses key challenges,
   such as address collisions, hardware limitations, multicast snooping
   inefficiencies, and the need to avoid manual configuration.  Based on
   these challenges, it derives requirements for a lightweight,
   decentralized protocol capable of dynamically allocating unique
   multicast group addresses without central coordination.

   The document presents explicit requirements covering discovery,
   allocation, conflict detection and resolution, and lease management.
   It also evaluates considerations specific to IPv6 and IPv4 multicast
   address ranges, and identifies approaches that are unsuited for
   zeroconf deployment.  This foundation serves as a reference for
   developing future multicast address allocation protocols that operate
   autonomously within local networks.
