Step-by-Step Guide: How to Use the IP Range Calculator
Using this IP Range Calculator is straightforward. Follow these steps to get accurate network details:
Step 1: Enter the IP Address
- Locate the IP Address field in the calculator.
- Enter the IP address you want to analyze, for example,
192.168.1.0. - Ensure that each octet is between 0 and 255 to avoid errors.
Step 2: Enter the Subnet Mask (CIDR)
- In the Subnet Mask field, input the CIDR value.
- CIDR values range from 1 to 32, representing the number of bits in the network portion.
- Example:
24corresponds to a subnet mask of255.255.255.0.
Step 3: Click “Calculate”
- Press the Calculate button to start the computation.
- A progress bar will appear, simulating the calculation process.
- Once complete, the results will display below the calculator.
Step 4: Review the Results
The calculator provides the following details:
- Network Address: The first IP in the subnet.
- Broadcast Address: The last IP in the subnet.
- Number of Hosts: Total usable IP addresses in the subnet.
- Subnet Mask: Full dotted-decimal format of the subnet mask.
Step 5: Copy or Share Results
- Use the Copy Results button to save the information to your clipboard.
- Use the Share Results button to send it via social media or supported apps.
Practical Example
Let’s say you are managing a small office network, and you need to subnet the IP range 192.168.10.0/28.
Step 1: Enter the IP: 192.168.10.0
Step 2: Enter the subnet mask: 28
Step 3: Click Calculate
Output:
- Network Address:
192.168.10.0 - Broadcast Address:
192.168.10.15 - Number of Hosts:
14 - Subnet Mask:
255.255.255.240
This calculation shows that the subnet can accommodate 14 usable IP addresses, perfect for a small office network.
