Episode 52: IPv4 Subnetting — The Process Step by Step

This episode walks through the process of IPv4 subnetting, a skill that requires practice and speed for the exam. It explains how to take a given network address and divide it into smaller subnets by borrowing bits from the host portion. Key steps include identifying the subnet mask, calculating block sizes, determining the number of subnets, and listing valid host ranges. Subnetting is one of the most calculation-heavy topics on the exam, and proficiency is essential.The discussion provides worked examples, such as dividing a 192.168.1.0/24 network into four equal subnets using a /26 mask. Troubleshooting examples include recognizing when overlapping subnets cause addressing conflicts or when improper mask selection leads to wasted address space. By practicing these processes, you will be able to solve subnetting problems efficiently, both under exam conditions and in real-world design tasks.
