Define Subnetting.- A subnet describes a set of networked computers which have common IP address routing prefix.
- Breaking the networking into smaller and more efficient subnets is known as subnetting.
- Subnetting prevents Ethernet packet collision which has excessive rates in a large network.
- Routers are used to manage the traffic and constitute borders among subnets.
- They are designed by accepting bits from the IP address's host part and using these bits to assign a number of smaller sub-networks inside the original network.
- It allows the organization to add sub-networks without acquiring a new network number via the Internet service provider (ISP).
- They help to reduce the network traffic and conceals network complexity.
- It is essential when a single network number has to be allocated over numerous segments of a local area network (LAN).
- It was designed for solving the shortage of IP addresses over the Internet.
