Step-by-Step Guide: How to Use the Network CIDR Calculator

Using the Network CIDR Calculator is straightforward. Follow these steps to determine your network details:

Step 1: Enter the IP Address

• Locate the IP Address field in the calculator form.
• Input a valid IP, e.g., 192.168.1.10.
• Ensure the format is correct: four numbers separated by periods.

Step 2: Enter the CIDR Prefix

• In the CIDR Prefix field, type a number between 0 and 32, e.g., 24.
• The CIDR prefix determines the subnet mask and size of the network.

Step 3: Calculate the Network

• Click the Calculate button.
• The tool will instantly display:
  • Network Address – the first IP in your network range.
  • Broadcast Address – the last IP in the network.
  • Subnet Mask – the mask corresponding to your CIDR prefix.
  • Number of Hosts – the total usable IP addresses in the network.

Step 4: Copy or Share Your Results

• Use the Copy Results button to save information for documentation or reporting.
• Click Share Results to share your network details via social media or supported platforms.

Step 5: Reset the Calculator

• Press the Reset button to clear the inputs and start a new calculation.

Practical Example

Let’s say you manage a network with the IP address 192.168.10.15 and a CIDR prefix of 28.

1. Enter 192.168.10.15 in the IP Address field.
2. Enter 28 in the CIDR Prefix field.
3. Click Calculate.

The tool will provide the following results:

• Network Address: 192.168.10.0
• Broadcast Address: 192.168.10.15
• Subnet Mask: 255.255.255.240
• Number of Hosts: 14

This helps you efficiently allocate IP addresses without guessing or errors.
