Class A Networks

What this Class A network addressing question tests

This is a foundational networking question that tests your understanding of IPv4 address allocation and subnet structure. It asks you to reason about the relationship between network bits and the total number of networks that can exist within a given address class.

To solve problems in this area, you need to understand how IPv4 addresses are partitioned into network and host portions, and how the number of bits allocated to each determines capacity. This knowledge is essential for anyone working with network infrastructure, routing, or systems that depend on IP address management.

• Binary representation of IPv4 addresses
• Network vs. host bit allocation
• Calculating address space from bit counts
• Reserved and special-use address ranges
