Before diving into subnetting, let's review IP addresses. An IP address is a 32-bit binary number that identifies a device on a network. It is typically represented in dotted decimal notation, with four octets (or bytes) separated by dots. For example, 192.168.1.1 is an IP address. To understand subnetting, let's consider an example: If

Suppose we have a Class C network with the IP address 192.168.1.0 and a default subnet mask of 255.255.255.0 . This means the first three octets ( 192.168.1 ) represent the network ID, and the last octet ( .0 ) represents the host ID. It is typically represented in dotted decimal notation,

Subnetting allows you to divide a large network into smaller sub-networks by applying a subnet mask. A subnet mask is a 32-bit binary number that determines which part of an IP address is the network ID and which part is the host ID.
