Episode 49: Understanding Classful IPv4 Addressing
20 Jul 2025
This episode reviews classful IPv4 addressing, a historical system that divided addresses into five classes: A, B, C, D, and E. Each class had predefined ranges and default subnet masks, such as Class A with 255.0.0.0 and Class C with 255.255.255.0. While classful addressing has been replaced by classless systems, it is still tested on the exam because many legacy references and concepts are rooted in these classifications.Examples include identifying which class an address belongs to, recognizing default subnet masks, and understanding why classful addressing led to inefficient use of address space. Exam questions may present addresses and require you to determine their class or recall default configurations. By reviewing these fundamentals, you ensure that you can handle both historical references and modern classless methods in exam scenarios.
