Divide an IPv4 address into a network and host portion. (Quick overview)

If an organization has lots of computers, or if its computers are geographically spread, it’s a good idea to divide its netwerk into smaller ones (subnets) connected by routers. The benefit of using subnets are less traffic (most traffic will stay on the local netwerk) and easier to isolate and identify a network problem.

The subnet mask splits an IPv4 address into a network and a host portion.

In this table below you can see how you can split your subnets using a subnet mask.
