Lesson - 2: IPv4 Adress Classes

🧠 Understand IPv4 Address Classes Like Never Before!

In this tutorial, we break down IPv4 address classes (A, B, C, D, and E) and explain how each class is defined based on the binary representation of the first octet.

🎯 What you'll learn in this video:

🔢 Class Ranges: The range of values for the first octet in each class (A to E)

🧮 Binary Breakdown: How to derive these ranges using binary bit positions (from 128 to 1)

📡 Multicast Insight: Why Class D is used for multicast traffic

🧪 Experimental Class: Why Class E is reserved for experimental purposes and not seen in live networks

🚫 Special Addresses: Why 0 and 127 are excluded from Class A usage

🔍 Perfect for:
