Network tools
Network calculator
The tool calculates the subnet range based on the IPv4 address and mask. You can enter only the address, the address with the CIDR prefix, or the address with a full decimal mask.

Specify `Address and mask`, e.g. `192.0.2.10`, `192.0.2.10/24` or `192.0.2.10/255.255.255.0`.
What is the Network Calculator used for?
The tool helps you quickly calculate the network address, broadcast, host range and number of available addresses in the IPv4 subnet.
Most common applications
You can check the range of addresses in the router's subnet, verify the server configuration, count the broadcast address or make sure how many hosts will fit in the selected mask.
Default behavior
If you enter just IPv4 without a mask, the tool will default to the `/24` prefix, as shown in the input example.
