About this Tool
This tool allows you to calculate network details from a CIDR notation, such as the network address, broadcast address, and available host range. CIDR, or Classless Inter-Domain Routing, is a method for allocating IP addresses and IP routing.
To use this tool, enter a valid CIDR notation in the input field provided, and click the "Calculate" button. The tool will display the results instantly, showing the netmask, total number of hosts, and other relevant network details.
For example, a CIDR of 192.168.1.0/24 will result in a netmask of 255.255.255.0 and 256 total hosts.
