Q
What is Subnetting?
A
Subnetting is a way of breaking a network into smaller groups to relieve congestion. A subnet is a logical subdivision of an IP network. The process of dividing a network into two or more networks is called subnetting. Security is another benefit of subnetting.
With a network that has been assigned from an ISP there are two portions.
The “network”
The “host”
ISP does not care what you do with host bits, but you can not modify the network bits.
