How to Use the Subnet Calculator
The IPv4 Subnet Calculator is designed to quickly determine the complete network profile of any given IP address and subnet mask. Follow the steps below to calculate your network ranges:
- Enter your IP Address: Type a valid IPv4 address (e.g.,
192.168.0.1) into the IP Address field. - Set the Subnet Mask or CIDR: You can either type the subnet mask directly (e.g.,
255.255.255.0) or use the interactive slider to adjust the CIDR prefix (e.g.,/24). - Analyze the Results: The calculator updates in real-time. Review your Network Address, Usable Host Range, and Broadcast Address immediately in the details panel above.
Example Calculation
For an input of IP 192.168.0.1 and a CIDR of /24, the output generated by the calculator will be:
| Network Address | 192.168.0.0/24 |
|---|---|
| First Usable IP | 192.168.0.1 |
| Last Usable IP | 192.168.0.254 |
| Broadcast Address | 192.168.0.255 |
| Total Usable Hosts | 254 |
| Total Available Host | 256 |
| Subnet Mask | 255.255.255.0 |
| Wildcard Mask | 0.0.0.255 |
| Binary Subnet Mask | 11111111.11111111.11111111.00000000 |
| IP Type | Private (Class C) |
