IPv4 subnetting test

How to Practice Subnetting:

1. Click on the [New IPv4 Address] Button:

• This will generate a random Target IP Address and CIDR (subnet mask).
• You will need to calculate the following attributes based on the given Target IP and CIDR:
  • Network Address
  • First Host
  • Last Host
  • Broadcast Address
  • Next Subnet

2. Enter Your Calculated Answers:

• In the table, there are fields where you can input your answers for each attribute.
• Use the provided input boxes for Network, First Host, Last Host, Broadcast, and Next Subnet.

3. Click [Check] to Verify Your Answer:

• After entering your answers, click the [Check] button to see if your calculations are correct.
• If your answer is correct, you will see a “YES” in the Correct? column.
• If your answer is incorrect, you will see a “NO”.

4. Click [Show] to View the Correct Answer:

• If you are unsure or want to see the correct answer, click the [Show] button next to each row.
• The correct answer will appear in the Answer column.

5. Check or Show All::

• At the bottom of the table, you can click [Check All] to check all of your answers at once.
• You can also click [Show All] to display all the correct answers for every field.

Tips for Subnetting Practice:

• Start with a lower CIDR value (e.g., /24 or /25) to practice smaller subnets if you are new to subnetting.
• Use the [Check] button frequently as you work through each field to verify your calculations before moving to the next.
• Familiarize yourself with key subnetting formulas and techniques, such as calculating the network address, first host, last host, and broadcast address.

Happy subnetting!
