What Is Subnet Id Used For?
A subnet, also called a subnet, is the subdivision of a large network. Subnets are a partition in a large internet protocol network into the small segments of the network. Over the internet, data is sent from one computer to another by internet protocol (IP) methods. One IP address is a specific identifier for a host on every computer.
Most organizations have used subnetting to divide the larger network into smaller networks to achieve efficient subnetting. The purpose of this splitting or subdivision is to decrease the traffic. This way traffic does not use unnecessary routes to speed up.
Subnet mask:
Every computer device has a specific IP address with two parts one is the client address and the second one is the network or server address. It is configured manually (static IP address) or by the DHCP server. Subnet mask divides the internet protocol address into two parts host and server address. Which part belongs to the device or which one belongs to the network is defined by the subnet mask. The device part is called as default gateway its function is to connect local devices to other networks. It means that when the local device sends information to the device by IP address on another network first it sends to the gateway then the gateway sends data to its destination outside the local network.
Benefits:
subnetting or subnet has many benefits which include as follows,
Uses:
Subnets are used for,
It allows the organization to decrease the threats by isolating compromised sections of the network.
Relieve network congestion:
If the traffic is shared among the same group of computers using the same subnets reduces the traffic network Without a subnet, all computers on the network see another computer’s data packets.
Every class has a fixed number of hosts if an administrator works on a class B or C and wants to allocate 150 hosts for three physical networks in three different cities, they need to divide a large network into smaller subnets allowing the administrator to use one class block on multiple networks.
