Multicast Address Range

Understanding IPv4 multicast address ranges

This is a straightforward easy networking question that tests foundational knowledge of IPv4 address classification. Multicast addressing is a core concept in network design, used whenever one sender needs to reach multiple receivers efficiently—common in video streaming, financial data feeds, and service discovery protocols.

To answer questions in this area, you need to recall how IPv4address space is partitioned into classes and reserved ranges. Multicast has its own designated block within the overall address space, distinct from unicast (standard host-to-host) and broadcast addressing. Understanding this partition is essential for anyone working on networked systems, whether you're building trading infrastructure, optimizing network protocols, or debugging connectivity issues.
