Classful vs Classless

Length: 00:06:00

Lesson Summary:

Classful IP addressing uses default subnet masks for IP address assignment. As a result, a lot of unused IP addresses were wasted. Classless IP addressing introduced the concept of variable length subnet masks. These masks allow us to divide or subnet a larger network into multiple smaller networks. In this lesson, we'll review classful vs classless IP addressing, to get a better understanding of how the concept works.
