{ "item_title" : "IPv4 Subnetting", "item_author" : [" Sundaram Mishra "], "item_description" : "Subnetting is one of the most important yet confusing topics in computer networking. Many learners struggle with binary calculations and complex formulas when trying to understand how IP networks are divided.This guide focuses on simplifying subnetting through a structured rule-based approach. Instead of relying heavily on binary calculations, the concepts are explained step by step so that readers can understand subnetting logically and solve problems faster.Unlike many traditional resources, this guide does not require prior knowledge of binary calculations. The methods explained here are designed to help learners solve subnetting problems without depending on binary conversions, making the learning process faster and more approachable.To achieve this, the guide introduces a structured 14-rule framework that simplifies subnetting into clear and practical steps. These rules help readers identify key elements such as subnet ranges, network addresses, and broadcast addresses quickly and confidently.Inside this guide, you will learn: - The fundamentals of subnet masks and IPv4 addressing- A structured 14-rule method for solving subnetting problems- How to identify the incomplete octet and magic number quickly- Fast methods to calculate subnet ranges, network address, and broadcast address- Shortcut tables for quick reference- Common mistakes beginners make while solving subnetting problems- Multiple practice questions to strengthen understandingThis guide is designed for: - Networking beginners- Students preparing for certifications such as CCNA, CompTIA Network+, and similar exams- IT learners who want to understand subnetting in a clear and practical wayThe goal of this guide is simple: To make subnetting logical, structured, and easy to solve without confusion or complex binary calculations.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/825/201/9798252019093_b.jpg", "price_data" : { "retail_price" : "9.99", "online_price" : "9.99", "our_price" : "9.99", "club_price" : "9.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
