Q
What is Subnetting?

You can break 256 blocks of IP’s into blocks such as 4 blocks of 64 IP’s or 8 blocks of 32 IP’s.

Q
How do you increase security via subnetting?
A
You can add policies and monitoring to each subnetted section. Each section can have its own white/blacklists and access control list.
Note: If an attacker breaks into a users computer, they will be trapped in that users subnet unless they gain access to other subnets.
