Subnetting Made Easy: IPv4 Subnetting Cheat Sheet & Practice Workbook

Subnetting Made Easy is a practical, no-fluff workbook built for anyone who needs IPv4 subnetting to actually make sense — networking students, IT support staff, and CCNA-level learners. It walks through IPv4 fundamentals, CIDR notation, an eight-step fast-subnetting method, VLSM, and real-world use cases, backed by eight fully worked examples and a 30-question practice set with a complete answer key. Every calculation has been checked for accuracy, including the /31 and /32 edge cases most guides skip. Designed as both a study guide and a permanent desk reference, with dedicated cheat-sheet pages for fast lookups during practice or exams.
