When multiple computers are linked together through a telecommunications system, it is called a computer network.

We can’t have direct conversations with every computer on a real network because those networks are so huge.

As a result, we partition networks into smaller units, which are known as subnetworks.

The necessity to allocate physical locations to various entities is still another justification.

One or more subnets form a local area network (LAN).

The prefix of an IP address is standard across all network devices in a subnet.

Routers provide communication between different networks.

It is also beneficial to performance to divide a network into smaller pieces.

You may find out what kind of network data is associated with a specific address block with this subnet calculator.

Although it is possible to mentally divide a huge network into smaller ones and assign IP address ranges to each team, it is always a good idea to have a way to verify your subnet calculations before setting them up in the router.
