IP subnetting is basically a process of dividing a large network into smaller, more manageable parts called subnets. This helps organize and secure networks by grouping devices logically.

Each device on a network has a unique IP address, consisting of two parts: the network portion and the host portion. A subnet mask is a 32-bit number that separates these two parts. For example, a subnet mask of 255.255.255.0 indicates that the first three octets (24 bits) represent the network, and the last octet (8 bits) represents the hosts.For Detail click on Readmore.
