Learn subnetting basics and c-class subnetting, analyze broadcast behavior, divide large networks into subnets, and convert between binary and decimal for network sizing.
Explore the difference between private and public IP addresses, how a local area network uses private addresses, and how public IPs and ISPs enable internet access.
Complete IPv4 Masterclass – From Basics to Advanced Subnetting and VLSM
Master IPv4 networking from the ground up with this comprehensive course designed for beginners, students, network engineers, system administrators, and IT professionals preparing for networking certifications.
In this course, you will gain a deep understanding of IPv4 addressing and subnetting through clear explanations, practical examples, and hands-on demonstrations. We start with the fundamentals of IPv4, including IP address structure, network and host portions, address classes, and subnet masks. You will then learn how to convert decimal numbers to binary and binary to decimal with simple techniques that make subnetting calculations easy.
The course covers Class A, Class B, and Class C subnetting in detail, along with real-world subnetting exercises to strengthen your skills. You will also master Variable Length Subnet Masking (VLSM), allowing you to design efficient IP addressing schemes for networks of any size. Through step-by-step demonstrations, you will learn subnet calculations, address allocation, and network optimization.
Additionally, the course introduces Reverse IP Engineering techniques to help you analyze and identify network information from IP addresses. You will also explore the differences between private and public IP addresses, NAT concepts, and practical deployment scenarios.
By the end of this course, you will be confident in designing, troubleshooting, and managing IPv4 networks and will have a solid foundation for certifications such as Cisco CCNA, Network+, and other networking programs.
