HOW TO SUBNET A GIVEN NETWORK ASSIGNMENT?

We have been assigned the network address 199.1.2.0.  Based on the chart below, we know this is a Class C address.  This is determined by observing the first octet of the IP address, which is 199.  This octet falls in between 192 and 223.

II. Network Addresses Design (in its entirety)
A. Subnetting Subnetting is a process of breaking a large network into small networks known as subnets.
Subnetting happens when we extend the default boundary of the subnet mask. Basically we
borrow host bits to create networks (i.e., subnets).
We have been assigned the network address 199.1.2.0. Based on the chart below, we know
this is a Class C address. This is determined by observing the first octet of the IP address,
which is 199. This octet falls in between 192 and 223.
Class Octet Decimal Range A 1 - 126 B 128 - 191 C 192 - 223 Each class has a predefined default subnet mask that tells us the octets, which are already part
of the network portion, as well as how many bits we have available to work with.
Class Subnet Mask Format A 255.0.0.0 Network.Host.Host.Host B 255.255.0.0 Network.Network.Host.Host C 255.255.255.0 Network.Network.Network.Host CIDR (Classless Inter Domain Routing)
CIDR is a slash notation of the subnet mask. CIDR tells us the number of on bits in a network
address.
● Class A has default subnet mask 255.0.0.0. that means first octet of the subnet mask has all on
bits. In slash notation it would be written as /8, means address has 8 bits on. ● Class B has default subnet mask 255.255.0.0. that means first two octets of the subnet mask
have all on bits. In slash notation it would be written as /16, means address has 16 bits on. ● Class C has default subnet mask 255.255.255.0. that means first three octets of the subnet
mask have all on bits. In slash notation it would be written as /24, means address has 24 bits
on.
Scenario The building will house four computer labs that will be used for instruction. In the building
diagrams above, the labs are labeled Classroom #2 and Classroom #4 on the first floor and
Classroom #1 and Classroom #5 on the second floor; each computer lab will have a closet. Each
lab will have 25 computers: 23 student computers, 1 instructor computer, and 1 server in the
closet for instructional use.
In addition, there will be a Student Computer Lab that will provide computer access to students to
do their homework. There will be 25 computers in this lab and a server in the closet. To allow
students access to library resources, the library will also have 20 computers for the general
public to use and 5 computers for library staff.
There needs to be separation between students, staff, and public access networks. The open WiFi also needs to be separate from the other three groupings.
Finally, there are various offices in the building. Each of these offices will have one computer for
staff use, with the exception of the admissions office, which will have five computers. There will
be two server rooms, one on the first floor and one on the second floor. Methodology
Given the aforementioned scenario, we are going to use the 192.168.0.0/24 network and create
a total of 8 subnets, with 25 hosts on each subnet. The chart below describes structures the
scenario to include each subnet and required hosts.
