Subnet Mask is an important component of all networking. Subnet Mask is a common subject that has to be learnt for all networking certifications such as MCSA, CCNA, and N+.
Subnet Mask, a short form of subnetwork mask,
a subnet mask, subnet, or subnetting is a method
of dividing a network of IP addresses into groups. Subnetting allows
each computer or networking device in its own subnet to communicate
with each other and still allow communication between subnets by
routing the traffic through the network router. By dividing a network
into subnets, it can improve network security and keep overall
network traffic balanced. A common example of a subnet mask for class
C IP addresses is 255.255.255.0 and is the default subnet mask for
many computers and network routers.
If you have the job of creating subnets for an
organization (an activity called subnetting) and specifying
subnet masks, your job may be simple or complicated depending on the
size and complexity of your organization and other factors.
The first subnet obtained
from subnetting has all bits in the subnet bit group set to zero (0).
It is therefore called subnet zero.The last subnet obtained from
subnetting has all bits in the subnet bit group set to one. It is
therefore called the all-ones subnet.
