An IP calculator is a tool for computing network parameters based on an IP address and subnet mask. It determines the available address range, broadcast address, and number of hosts.
| Term | Description | Example |
|---|---|---|
| IP Address | Unique device identifier | 192.168.1.100 |
| Subnet Mask | Defines network boundaries | 255.255.255.0 |
| CIDR Notation | Short mask notation | /24 |
| Network Address | First address of the subnet | 192.168.1.0 |
| Broadcast Address | Last address of the subnet | 192.168.1.255 |
Enter the device IP address (e.g., 192.168.1.100)
Specify the subnet mask or CIDR prefix (/24)
Get the result: network address, host range, broadcast address
Use the data to configure network equipment
Reserved for local networks: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These addresses are not routed on the internet.
Calculate network parameters with the IP Calculator.
