NETWORK ADDRESSING
Network IP Addressing
This paper is mainly focused on the specification of the network configurations for
the school network. This paper introduces a subnet chart which will list all the required
network specifications for addressing. This report lists a security section that will be utilized
in the network infrastructure. This report has also discussed about the hardware specifications
that will be used for the system.

The process of subdividing a network to smaller subnetworks (subnets) is referred to
as subnetting. It is basically used for dividing the whole IP address range into similar ports
which can be used for going into each device in the network. It is also used for addressing the
computers belonging to a particular subnet with an identical and similar IP address. This
process is carried out when there is an extension of subnet mast default boundary. The mask
that subdivides IP address to create a network and host addresses is called subnet mask. A
subnet mask is used to mask the IP address and divide it into two various types of addresses,
the host address and the network address.
SECTION 2: Network Security
Firewall Selection
A firewall protects local networks from the outside global networks. That is, all data
packets entering or leaving the network have to pass through the firewall and it screens them
to pass through, modify or block them. A properly implemented firewall can be extremely
effective in reducing or eliminating many network threats [1].
The segmented network architecture proposed for the building is very efficient in
controlling threats to the network. This is due to the subdividing the network into sub-
networks which allows prevention of hosts belonging to a subnetwork invisible from outside
world. The most efficient types of firewalls to implement in this network are packet filtering
