This tool streamlines the process of calculating network addresses, broadcast addresses, and usable IP ranges, saving time and reducing errors in network management.
The DNS Calculator is designed for efficiency and simplicity, offering a clean interface and step-by-step results for both novice and advanced users. Whether you’re subnetting a network for the first time or verifying IP ranges in a large enterprise setup, this tool provides precise calculations at your fingertips.
How to Use the DNS Calculator: Step-by-Step
Using the DNS Calculator is straightforward. Follow these steps to get accurate results:
- Access the Calculator
Open the DNS Calculator interface. You will see input fields labeled for the IP address and subnet mask. - Enter the IP Address
In the designated field, type the IP address you want to calculate. Ensure it is in the standard IPv4 format (e.g., 192.168.1.1). - Enter the Subnet Mask
Input the subnet mask associated with your network. This could be in standard format (e.g., 255.255.255.0) or CIDR notation (e.g., /24). - Calculate the DNS Information
Click the “Calculate” button. The tool will process the IP and subnet information to generate results, including:- Network address
- Broadcast address
- First usable IP
- Last usable IP
- Total number of hosts
- View and Use Results
Your results will appear in a clear, organized layout. You can copy or share the output using the provided buttons. - Reset if Needed
If you need to perform another calculation, click the “Reset” button to clear the fields and start fresh.
Practical Example
Imagine you are managing a small office network with the IP range 192.168.10.0/24. You want to determine the network details to configure a router and assign IP addresses efficiently.
- Enter
192.168.10.0in the IP address field. - Enter
255.255.255.0as the subnet mask. - Click Calculate.
The DNS Calculator will display:
- Network Address: 192.168.10.0
- Broadcast Address: 192.168.10.255
- First Usable IP: 192.168.10.1
- Last Usable IP: 192.168.10.254
- Total Hosts: 254
This information allows you to assign IPs without conflicts, plan network devices, and ensure proper communication between nodes.
