Course Description

In this lesson, we'll take a look at what subnetting is and why we use it. Remember our class A, B and C networks? Class A: 16777216 addresses in total. Class B: 65536 addresses in total. Class C: 256 addresses in total. A subnet is a sub-network of a network that falls within the class A, B or C ra

Subnetting is the art of creating two or more subnets out of a single network address. In these lessons you will learn how to do subnetting in binary or decimal and how to become really fast at it. You will also learn how to calculate hexadecimal addresses which is useful for IPv6.
