Subnetting is the process of taking one IP network address and dividing it into two or more sub-networks to create smaller network segments. It is done to add more local area networks, free up bandwidth, and localize departments. An IP address is made up of 32 bits divided into four octets, and subnetting works by splitting the address into a network and host portion to establish multiple sub-networks.

2. What is Subnetting?Subnetting is the process of taking one IP network address and creating two or more sub-addresses. By changing the subnet mask, you are now able to create/produce/make an even number of mini/smaller network that each has their own range of corresponding IP addresses.

3. When to Subnet?It is done when you want to add more LAN segment to the current network. Free up bandwidthLocalizing department (Accounting, HR, Sales)

4. How does it work?An IP address is a 32 bit number divided into 4 sections of 8 bits called octets.The address can also be split into a network and host portion.
