IP address broadly fall into two categories: Classful and Classless.
In this lesson, I dive deep into the Classification of Classful IP addresses. I have explained how the first Octet is used to divide IP addresses into various classes, Class - A, Class -B, Class - C and Class - D.
In the Classful scheme
Class - A: 0 to 127
Class - B: 128 to 191
Class - C: 192 to 223
Class - D: 224 to 239
After completing this tutorial, you will be able to
a) Successfully identify the Class of a given IP address.
b) Successfully explain the logic on how the various Classes are derived.
