Assignment: Subnetting In this assignment, you are required to re-organize our Department's wired computer network. The first part of the assignment familiarizes you with the current network. The second part requires you to divide the current network into two sub-networks: a small one for the staff and a larger one for the students.

Part 1 Our senior academic Prof Dumbledore's Departmental desktop has the IP address 26.221.51.236/21. Based on this, please answer the following questions.

What is the network address of this network? [1 mark]

What is the network mask of this network? [1 mark]

What is the broadcast address in this network? [1 mark]

What is the lowest host IP address in this network? [1 mark]

Assuming that the router is assigned the largest available IP address in the range, what is the IP address of this network's router? [1 mark]

What is the largest host IP address in this network, excluding the router? [1 mark]

What is the maximum number of hosts that can be supported in this network? [1 mark]

Part 2

In this part, you are asked to partition the Departmental network address block to create separate staff and student sub-networks. Your network must be able to support up to 143 machines on the staff network (not counting the router) and up to 654 machines on the student network (also not counting the router). You must choose the largest possible network address for the student network. You must then choose the smallest possible network address for the staff network. You must also choose the smallest possible size for the two sub-networks so that a visitor/guest network can be established in the future with the remaining network capacity.

Part 2A

Based on your partition, please answer the following questions that relate to the student network.

What is the network address of this network? [1 mark]

What is the network mask of this network? [1 mark]

What is the broadcast address in this network? [1 mark]

What is the lowest host IP address in this network? [1 mark]

Assuming that the router is assigned the largest available IP address in the range, what is the IP address of this network's router? [1 mark]

What is the largest host IP address in this network, excluding the router? [1 mark]

What is the maximum number of hosts that can be supported in this network? [1 mark]

Part 2B

Based on your partition, please answer the following questions that relate to the staff network.

What is the network address of this network? [1 mark]

What is the network mask of this network? [1 mark]

What is the broadcast address in this network? [1 mark]

What is the lowest host IP address in this network? [1 mark]

Assuming that the router is assigned the largest available IP address in the range, what is the IP address of this network's router? [1 mark]

What is the largest host IP address in this network, excluding the router? [1 mark]

IP address 26.221.51.236/21.

Part 1.

What is the network address of this network? :

To get network address of the network bitwise AND ip address with subnet mask.

00011010 . 11011101. 00110011. 00100100 [IP]

11111111. 11111111. 11111000. 00000000 [Mask]

= 00011010.11011101.00110000.00000000 = 26.221.48.0

What is the network mask of this network (/21) :

11111111.11111111.11111000.00000000 = 255.255.248.0

What is the broadcast address in this network?:

In directed broadcast address of the network all the host bits in the network address are 1 :  

Network address of the network :  00011010.11011101.00110000.00000000 = 26.221.48.0

The bold part shows the host bits. Therefore Broadcast address =   00011010.11011101.00110111.11111111 = 26.221.55.255

What is the lowest host IP address in this network? [1 mark]

Network address of the network :  00011010.11011101.00110000.00000000

Lowest IP address of the network : 00011010.11011101.00110000.00000001 = 26.221.48.1

Assuming that the router is assigned the largest available IP address in the range, what is the IP address of this network's router? [1 mark]

Largest available IP address in the range (all host bits as1): 00011010.11011101.00110111.11111111 = 26.221.55.255

What is the largest host IP address in this network, excluding the router? [1 mark]

Largest host IP address in this network : 00011010.11011101.00110111.11111110 = 26.221.55.254

What is the maximum number of hosts that can be supported in this network? [1 mark]

No. of host bits = 32-21 = 11

maximum number of hosts that can be supported = 211 -2 = 2048-2 =2046
