Multicast Addressing

What this IPv4 multicast addressing question tests

This is an easy networking question that checks your understanding of IP address space allocation and the structure of multicast addresses in IPv4. It appears in technical screening for roles that touch network protocols, systems engineering, or infrastructure work.

To answer correctly, you need to recall how IPv4 address classes are defined, which bits are reserved for class D (multicast), and how many unique addresses that reserved range contains. The question rewards precision: you must convert your understanding of bit allocation into an exact count.
