Find the Subnet ID (Class C)
Learn how to find the subnet ID, broadcast address, and usable hosts from any IP and mask using a simple method that avoids binary math and speeds up subnetting.

Converting IP addresses into Binary
In this lesson, we will learn a technique called the positional notation method. The value of each digit in a binary number is determined by its position in the table. The sum of all these column values for each digit gives the decimal representation of the binary number.
Why do we need IP Subnetting?
In this lesson, we will begin our discussion on IPv4 addressing and subnetting. We will see why we need to subdivide classful IP networks into subnets.
