Subnet mask is used to identify a particular network within the organization. Subnet
mask can be variable and it is determined by how the organization divides its network.
From the example above, to find a particular network within this organization, we can
use the first three portion of the IP address. Thus, its subnet mask is defined as
255.255.255.0
