Introduction
In this article we will use ChatGPT to learn the subnetting concepts for Ipv4 address. In our article we have covered how to use ChatGPT to create subnets based on our request. You happened to have missed our earlier article , please check the link below
Now we know that ChatGPT creates subnets as per our request, but do we know that it can also teach us how to do subnetting with step by step explanations? Along with that it can also check the subnetting examples we tried and provide feedback.
Practical example on how to use ChatGPT as a Subnetting Tutor
Simple teaching request to ChatGPT
In this example , we requested ChatGPT to train us on how to create subnets which have at least 24 ips from the network 10.0.0.0/24 and we can see that the chatGPT was able to provide us with the Step by step explanation on how to perform that subnetting , if we go by the steps we can easily create one ourselves. Also the steps provided seem to be very easy to follow.
#Request to ChatGPT Can you teach me how to do subnetting to create a subnet with atleast 24 ips from this network 10.0.0.0/24
#response from ChatGPT
Certainly! I’d be happy to teach you how to perform subnetting to create a subnet with at least 24 IP addresses from the network 10.0.0.0/24.
Subnetting involves dividing a larger network into smaller subnetworks, or subnets, by borrowing bits from the host portion of the IP address. In this case, we want to create a subnet with at least 24 IP addresses, so we need to determine the number of additional bits required to accommodate that many hosts.
Step 1: Determine the required number of hosts
To accommodate at least 24 hosts, we need to find the smallest power of 2 that is equal to or greater than 24. In this case, 2^5 = 32, so we’ll need at least 5 additional bits for the host portion.
Step 2: Determine the new subnet mask
The original subnet mask for the network 10.0.0.0/24 is 255.255.255.0. To create a new subnet with 5 additional bits for hosts, we need to convert these bits to zeros in the subnet mask.
The subnet mask for the new subnet can be calculated as follows:
Convert the number of host bits required to a decimal value. In this case, we need 5 host bits, so the decimal value is 2^5 = 32.
Subtract the decimal value from 256 (2^8) to determine the subnet mask value. In this case, 256 – 32 = 224.
Therefore, the new subnet mask for the subnet with at least 24 IPs will be 255.255.255.224.
Step 3: Determine the network and broadcast addresses
To calculate the network and broadcast addresses for the new subnet, we need to understand the binary representation of the subnet mask.
The binary representation of the new subnet mask (255.255.255.224) is:
11111111.11111111.11111111.11100000
To find the network address, perform a logical “AND” operation between the IP address and the subnet mask:
10.0.0.0 (binary: 00001010.00000000.00000000.00000000)
255.255.255.224 (binary: 11111111.11111111.11111111.11100000)
Network address: 10.0.0.0
To find the broadcast address, flip all the host bits in the subnet mask to “1” and perform a logical “OR” operation with the network address:
10.0.0.0 (binary: 00001010.00000000.00000000.00000000)
0.0.0.31 (binary: 00000000.00000000.00000000.00011111)
Broadcast address: 10.0.0.31
Step 4: Determine the usable IP range
The usable IP range within the subnet is the range between the network address and the broadcast address, excluding the network and broadcast addresses themselves.
In this case, the usable IP range for the subnet is from 10.0.0.1 to 10.0.0.30, as 10.0.0.0 is the network address and 10.0.0.31 is the broadcast address.
That’s it! You have successfully subnetted the network 10.0.0.0/24 to create a subnet with at least 24 IP addresses using the subnet mask 255.255.255.224
Complex teaching request to ChatGPT
In this example , we requested ChatGPT to train us on how to create subnets which have at least 24 ips from the network 10.0.0.128/25 and we can see that the chatGPT was able to provide us with the Step by step explanation on how to perform that subnetting , if we go by the steps we can easily create one ourselves. Also the steps provided seem to be very easy to follow.
#Request to chatGPT can you teach me to create subnet of atleast 24 Ips if the network is 10.0.0.128/25
#Response from chatGPT
Certainly! To create a subnet with at least 24 IP addresses from the network 10.0.0.128/25, we’ll follow similar steps as before.
Step 1: Determine the required number of hosts
To accommodate at least 24 hosts, we need to find the smallest power of 2 that is equal to or greater than 24. In this case, 2^5 = 32, so we’ll need at least 5 additional bits for the host portion.
Step 2: Determine the new subnet mask
The original subnet mask for the network 10.0.0.128/25 is 255.255.255.128. To create a new subnet with 5 additional bits for hosts, we need to convert these bits to zeros in the subnet mask.
The subnet mask for the new subnet can be calculated as follows:
Convert the number of host bits required to a decimal value. In this case, we need 5 host bits, so the decimal value is 2^5 = 32.
Subtract the decimal value from 256 (2^8) to determine the subnet mask value. In this case, 256 – 32 = 224.
Therefore, the new subnet mask for the subnet with at least 24 IPs will be 255.255.255.224.
Step 3: Determine the network and broadcast addresses
To calculate the network and broadcast addresses for the new subnet, we need to understand the binary representation of the subnet mask.
The binary representation of the new subnet mask (255.255.255.224) is:
11111111.11111111.11111111.11100000
To find the network address, perform a logical “AND” operation between the IP address and the subnet mask:
10.0.0.128 (binary: 00001010.00000000.00000000.10000000)
255.255.255.224 (binary: 11111111.11111111.11111111.11100000)
Network address: 10.0.0.128
To find the broadcast address, flip all the host bits in the subnet mask to “1” and perform a logical “OR” operation with the network address:
10.0.0.128 (binary: 00001010.00000000.00000000.10000000)
0.0.0.31 (binary: 00000000.00000000.00000000.00011111)
Broadcast address: 10.0.0.159
Step 4: Determine the usable IP range
The usable IP range within the subnet is the range between the network address and the broadcast address, excluding the network and broadcast addresses themselves.
In this case, the usable IP range for the subnet is from 10.0.0.129 to 10.0.0.158, as 10.0.0.128 is the network address and 10.0.0.159 is the broadcast address.
That’s it! You have successfully subnetted the network 10.0.0.128/25 to create a subnet with at least 24 IP addresses using the subnet mask 255.255.255.224. The usable IP range for this subnet is 10.0.0.129 to 10.0.0.158.
Request to ChatGPT to provide some questions for practice
In this example , we requested ChatGPT to provide us with some practice subnetting questions with keys. As every learning needs some ways to check whether our understanding is correct , these questions help a lot with that.
#Request to chatGPT provide me some example questions to work it out to learn subnetting better and also provide short answers with steps as a Key
#Response from ChatGPT
Sure! Here are some example questions to help you practice subnetting, along with their short answers and steps:
Question 1:
Given the network 192.168.0.0/24, create a subnet with at least 50 IP addresses.
Answer 1:
Step 1: Determine the required number of hosts. We need to accommodate at least 50 hosts, which requires 6 additional bits (2^6 = 64).
Step 2: Determine the new subnet mask. Subtracting 64 from 256 gives us 192, so the new subnet mask is 255.255.255.192.
Step 3: Determine the network address. Perform a logical “AND” operation between the IP address (192.168.0.0) and the subnet mask (255.255.255.192) to get the network address, which is 192.168.0.0.
Step 4: Determine the broadcast address. Flip all the host bits in the subnet mask to “1” and perform a logical “OR” operation with the network address to get the broadcast address. In this case, it is 192.168.0.63.
Step 5: Determine the usable IP range. The usable IP range is from the network address + 1 to the broadcast address – 1. So, the usable IP range for this subnet is 192.168.0.1 to 192.168.0.62.

Checking our answers with ChatGPT to fix our mistakes
After getting the questions from the ChatGPT we tried some subnetting and requested it to verify whether our answers were correct. ChatGPT was able to help us rectify our mistakes if its incorrect by providing right answers and also it confirms if our subnets are correct
#Request to chatGPT Can you check whether the subnets I prepared seem to be correct ? Subnet mask: /26 Network address: 192.168.0.0/26 Broadcast address: 192.168.0.63/26 Usable Ips : 192.168.0.1 to 192.168.0.62
#Response from chatGPT
Based on the information you provided, it seems that you have correctly calculated the subnet using a subnet mask of /26 for the network address 192.168.0.0. Here’s a breakdown of your subnet:
Subnet mask: /26
Network address: 192.168.0.0/26
Broadcast address: 192.168.0.63/26
Usable IPs: 192.168.0.1 to 192.168.0.62
The network address, broadcast address, and usable IP range you have determined align with the subnet mask /26. Well done!
# Request to ChatGPT ( testing with a wrong answer this time ) Can you check whether the subnets I prepared seem to be correct ? Subnet mask: /27 Network address: 192.168.0.0/27 Broadcast address: 192.168.0.63/27 Usable Ips : 192.168.0.1 to 192.168.0.62
#Response from ChatGPT ( it pinpoints our mistakes and also provides the correct answer )
Based on the information you provided, it seems that you have correctly calculated the subnet using a subnet mask of /27 for the network address 192.168.0.0. Here’s a breakdown of your subnet:
Subnet mask: /27
Network address: 192.168.0.0/27
Broadcast address: 192.168.0.31/27
Usable IPs: 192.168.0.1 to 192.168.0.30
Please note that the broadcast address you mentioned, 192.168.0.63/27, is not correct for the given subnet. The correct broadcast address for a /27 subnet is 192.168.0.31/27. The usable IP range you mentioned, 192.168.0.1 to 192.168.0.62, also does not align with the subnet mask /27. The correct usable IP range for the subnet is 192.168.0.1 to 192.168.0.30.
Therefore, the corrected information for the subnet you prepared is as follows:
Subnet mask: /27
Network address: 192.168.0.0/27
Broadcast address: 192.168.0.31/27
Usable IPs: 192.168.0.1 to 192.168.0.30
Please verify your calculations based on this information.
