THE ART OF SUBNETTING
Subnetting is an art, knowing how subnetting operates and how is achieved you will notice it is an Art.
What is Subnetting?
Subnetting is the strategy used to partition a single physical network into more than one smaller logical sub-networks (subnets). An IP address includes a network segment and a host segment. Subnets 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. Subnetting allows an organization to add sub-networks without the need to acquire a new network number via the Internet service provider (ISP). Subnetting helps to reduce the network traffic and conceals network complexity. Subnetting is essential when a single network number has to be allocated over numerous segments of a local area network (LAN).
Subnets were initially designed for solving the shortage of IP addresses over the Internet.
What is the main goal of subnetting
One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic. This way, traffic doesn’t have to flow through unnecessary routs, increasing network speeds. Subnetting, the segmentation of a network address space, improves address allocation efficiency.
- Improve network performance and speed. A single broadcast packet sends out information that reaches every device connected to that network because each device has an entry point into the network. …
- Reduce network congestion. …
- Boost network security. …
- Control network growth. …
- Ease administration.

Get subnetting cheat sheets to help you master and understand how it works and how subnets are achieved.
What is the simplest way to calculate subnetting?
Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2⁵) and you will find that the result is 32 subnets.
