VLSM Example You will use Cisco Packet Tracer to do your homework for tonight. You will create
a packet using the topology as described in the exercise. You will then label the IP
Addresses, as described in the assignment. I have provided you with an example,
to help you visualize how the topology shall look. For the VLSM packet exercise,
I have provided an example for you to follow:
If you recall, in class, I told you to write out the available hosts, as it will help you
to visually “see” how this tree is constructed. Focus on the example above. The
example above uses a Class C network address of 192.168.16.0. You then were
given the following information:
• 120 hosts in Washington, DC
• 60 hosts in Baltimore
• 20 hosts in Frederick.
As you know, the connections between Washington, DC require 2 hosts, or /30.
Also, the connections between Washington DC require 2 hosts as well. Based on
these requirements, we know the following:
Page 2 of 3
• Washington, DC will be 192.168.16.0 /25
• DC to Frederick connection will be 192.168.16.228 /30
• Frederick will be 192.168.16.192 /27
• DC to Baltimore will be 192.168.16.224 /30
• Baltimore will be 192.168.16.128 /26
To understand, will start with Washington, DC by writing out the available hosts and
networks with this subnet. That said, the Washington, DC ranges will be as follows:
• 2 extra networks with 128 hosts per network means your ranges will be
192.168.16.0 thru 192.168.16.127 (0 is the network and 127 is the broadcast
address) (usable hosts are 1 thru 127)
• 192.168.16.128 thru 192.168.16.255 (128 is the network and 255 is the
broadcast address) (usable hosts are 129 thru 254)
At this point, you must “pass” the additional network along to Baltimore, because it
has the 2nd highest number of hosts, meaning that they will inherit the
192.168.16.128 network.
Because Baltimore requires 4 hosts with 64 hosts per network (or /26), you now have
192.168.16.128 /26. You will continue this process until you have distributed all of
the hosts.
If you needed anything between /17 to /23 on a 192.168.16.224 network, it means,
the third octet (the “16”) can be any number from 0 to 255. From there, you will
use the same process; this time, however, the third AND fourth octet will be affected.
OTHER HELPFUL POINTS:
Remember the following:
Page 3 of 3
Network 2 4 8 16 32 64 128 256
192 = 1 1 0 0 0 0 0 0 Hosts 128 64 32 16 8 4 2 1
So, a network ending in 192 translates into 4 extra networks and 64 extra hosts. A
network ending in 224 (11100000) means 8 extra networks and 32 extra hosts.

Homework (Part 2)
Before attempting to do this exercise, please view the following video:
https://www.youtube.com/watch?v=sKzraLlFuGQ
Hopefully, you noticed the fact that they gave direct details about the incident being described.
They also gave direct answers about the incident, and NOT general information about crime
scenes. Your answers MUST be the same way.
For this assignment, you are to reflect on Packet Tracer assignment and answer the following:
Define malware. Overall, how will malware affect the topology that you just created.
Define adware, bots, bugs, ransomware, rootkits, trojans, worms, spyware and malware.
Describe how they can infect this network topology and how a Network Forensics
Examiner can discover and preserve them as evidence.
What is a network intrusion and how can a network intrusion occur in this topology? How
are adware, bots, bugs, ransomware, rootkits, trojans, worms, spyware, and malware
related to network intrusions?
What is an incident report? How will an incident report be useful in your forensic
examination?
Using the format that was provided with your first assignment, answer those questions in a short
two to three-page report, incorporating all of the above information into your report. Answers
that do not follow the scope, or provide general information will lose points.

Homework 3
This information will help you with your first in-class lab. Watch both videos. Both videos are
a part of one single incident. After reviewing the videos, write a narrative on everything that
occurred. Using the format originally shown, you will create a report in Word. You will also
need this report for class, as you will need to use this for your in-class lab.
