Question 1
The major difference among classful routing and classless routing is that in
classful routing VLMS is not supported but classless routing supports the
VLMS process. Moreover, classful routing needs more bandwidth but
classless routing does not require a larger bandwidth. In the relation of
classful hello signals are not utilized by the consumers but in classless, hello
signals are utilized.
Question 2
It is identified that block size in the case of class A is too higher for any
business community and most addresses in this class are wasted and not
utilized by the consumers. However, the size of the class C address is 256
which is small for the companies. Therefore, a medium-size does not require
a block of class C.
Question 3
In IPv4 addressing, a mask is used to hides the network part of a computing
system and leaves only the host part as the machine identifier. Moreover, it
utilizes a similar format of IPv4 address [1].
Question 4
A network address is defined as a process used for finding a communication
node from the computing networks and devices. In the block of address, a
network address is the first address. The consumers can determine the
length (n) from the mask and the network address can be obtained by
keeping then-left most bits of the provided address and setting the
remaining 32-n bits as 0.

Question 5
Sub-netting is a process where a huge address block is categorized into
numerous parts and each part may be assigned to a lesser network defined
as a subnet. It is observed that a sub-net mark has larger consecutive 1s as
compared with the evasion mask [2].
Question 6
NAT is defined as a network address translation that is used for remapping
one IP address into another by changing the information of the network
address. It enables consumers to have a huge set of addresses that helps to
address repletion and manage issues effectively.
Question 7
In the case of connection, oriented service authentication is required but in
the connectionless process, the consumers do not require any
authentication. In terms of reliability connection, oriented services are more
reliable as compared with the connectionless services [3].
Question 8
Fragmentation is defined as the condition of a dick where data files are
categorized into pieces around the disk. It is required for handling
communication-related issues and managing the performance-related
problems in an effective manner [4].
Question 9
There are various kinds of strategies used to perform the transition between
the IPv4 and IPv6 address which are highlighted below:
 Dual stack routers
 Tunneling process
 NAT protocol translation
