Sample IP Addressing Question (ChatGPT)

Question 1

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

a) What is the total number of sub-networks in the hospital?

Answer 1

7+1 = 8

Question 2

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

b) What is the number of subnet bits required to create the subnets?

Answer 2

8 = 2^?
2^3 = 8
3 subnet bits

Question 3

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

c) What is the new subnet mask?

Answer 3

New subnet mask: 1111 1111 . 1111 1111 . 1110 0000 . 0000

255.255.224.0

Question 4

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

d) What is the subnet address of the first sub-network?

Answer 4

1110 0000 . 0000 0000

001 is subnet address of first sub network

Question 5

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

e) What is the first valid IP address in the first sub-network?

Answer 5

The first valid IP address is obtained by adding 1 to the subnet address.

001

First Valid IP = Subnet Address + 1 = 153.20.32.1

Question 6

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

f) What is the 10th valid IP address in the first sub-network?

Answer 6

The 10th valid IP address is obtained by adding 9 to the subnet address.

001

10th Valid IP = Subnet Address + 10 = 153.20.32.10

Question 7

You are responsible for designing a hospital network with one administrative
department and seven clinical departments. The hospital network is given the IP address 153.20.0.0 / 16.

g) What is the broadcast address for the first-sub network?

Answer 7

The broadcast address can be calculated by taking the complement of the subnet mask and performing a logical OR operation with the subnet address.

Broadcast Address = Subnet Address OR (NOT Subnet Mask)

Broadcast Address = 153.20.63.255
