Answer of question 1:
In classful addressing system, the available IP addresses are divided into five classes. A, B,
C, D, and E where the classes A, B and C are used more often as the class D is for the
multicast and it is hardly used. Every IP addresses belongs to any particular class and this is
the reason why these are called classful addresses.
The Classless addressing is the method of allocating and specifying the internet addresses
that are utilised in the inter-domain routing more flexibly.
Answer of question 2:
In any class A network, the primary eight bits, or first dotted decimal, is the part of the
network of address with remaining part of address that is being the part of the host of the
address. There are 128 possible Class A network. It starts from 0.0.0.0 to 127.0.0.0 and the
initial few addresses are not used by anyone, so they are mostly wasted.
Answer of question 3:
A subnet mask separates the IP address into any subnet and the host address, if there is a
requirement of any subnetwork. This is called the subnet mask as it is utilised for identifying
the network address of any IP address by the performing of any bitwise AND operation on
netmask.
Answer of question 4:
Any network address is the identifier for any node or any host on any network block. The
designing of the network addresses is done to be unique identifiers all through the network,
even though some of the networks allows for the private and local addresses or the locally
administered addresses that might not be unique. In some of the cases, the hosts of the
network might not have network address that is more than one and each of the interface of

network might not be exclusively identified (Kreutz et al., 2015). The process of finding any
network address from a block of address can be understood from this example:
The addresses in the block can be converted into IPv4 notation gives range 172.41.100.32 -
172.41.100.47.
The addresses number can be calculated directly from CIDR (/28): 2³² ²⁸ = 2⁴ = 16.⁻²⁸ = 2⁴ = 16.
Answer of question 5:
The subnetting is a strategy that is used for partitioning any single physical network into
several minor logical sub-networks. The designing of subnets is done with accepting the bits
from any host part of the IP address. Any subnet mask consists of more consecutive 1s than
any corresponding default mask.
Answer of question 6:
NAT is referred to the process of assigning any public address to any computer where the
network, commonly a firewall inside the private network (Conti & Giordano, 2014). The
process of NAT is the method of remapping any space of IP address into another using the
modification of the information of the network address in the header of IP of the packets
while it is being transmitted across any routing device.
Answer of question 7:
Connection oriented requires the session connection to be established prior any transmission
of data is done. This methods is considered to be any reliable network service.
Connectionless services are the services that does not require any kind of session connection
among the receiver and sender.
