FINAL PROJECT (Instructions & Guidelines)
As a part of the assigned work for this course, you are required to complete a project that is
based on the material of this course. The premise of the project is closely related to some aspect
of the course material but may explore an avenue that was left un-addressed in class.

Network topologies
Problem 1. Consider an Ethernet network with three hosts, Host A, Host B, and Host C as shown in Figure 1. No machine is configured as an IP router, and there is no IP router on this network. Assume that the IP addresses and subnet masks are as shown in the figure
For each of the following IP datagram transmissions, describe if the transmissions will be successful. If a transmission will not work, provide an explanation:
(a) Host C sends an IP datagram to Host A (does not work\ works)
(b) Host A sends an IP datagram to Host B (does not work\ works)
(c) Host A sends an IP datagram to Host C (does not work\ works)
(d) Host B sends an IP datagram to Host A (does not work\ works) (e) Host B sends an IP datagram to Host C (does not work\ works)
Problem 2. Consider the 128.100.12.0/18 block of IP addresses. This block of addresses must be divided into five subnetworks that have each at least 530 IP addresses.
a) Give the subnet mask of the four new subnetworks.
b) Specify the network address and the network prefix for each subnetwork.
c) Specify the broadcast IP address for each subnetwork
192.0.30.87 192.0.30.92 192.0.3.201 255.255.255. 0 255.255.255. 0 255.255.255.240
Problem 3. Select a subnet mask for 10.0.0.0/12 so that there will be at least 13,000 subnets with at least 400 host addressed on each subnet.
Problem 4. Assume that you have been assigned the 200.35.10.0/28 network block.
a) Define an extended-network-prefix that allows the creation of 21 hosts on each subnet.
b) What is the maximum number of hosts that can be assigned to each subnet?
c) What is the maximum number of subnets that can be defined?
d) Specify the subnets of 200.35.1.0/28 in binary format and dotted decimal notation.
e) List range of host addresses that can be assigned to Subnet #6 (200.35.10.192/28)
f) What is the broadcast address for subnet 200.35.10.192/28?
Problem 5. For my research, I have requested a block of IP addresses from the Saskatchewan polytechnic. In reply to my request (on Nov. 15, 2022) I received the following response:
Information for new network: Base address: 142.150.13.0
Network mask: 255.255.255.224 Broadcast address: 142.150.13.31
Reserved Router address: 142.150.13.1
This network should go on:
bcit-ece-tier3-if.gw switch and our bcit router.
a) What is the address of the assigned subnetwork and what is the extended network prefix? b) Which IP addresses can I use to configure the computers in my lab?
c) How do I configure the IP address, default gateway, and subnet mask on my computers? d) Does the assigned address block use subnetting? Do I need to care?
e) What is the meaning and relevance of the last two lines in the above message (about the switch and the bcit router)?
f) If subnetting is used, how many bits of the host number are used to designate the subnet, and what is the IP address of the network that is divided into subnets (without subnetting)?
g) What is the role of the “reserved router address”? Why is this information important?
h) Do I need to set up a router in my lab?
i) Suppose I wanted to do subdivide the assigned address block into 4 smaller subnetworks of equal size. How large are these networks, and how many IP addresses can I assign in each subnetwork? What other equipment and configurations are necessary?
