CIDR/Netmask

What is this tool?

This tool is designed to show you information about a CIDR range, like 192.168.0.0/16 (such as the netmask to use, and the lowest and highest IPs in the range). However, you can also enter a single IP address such as 192.168.114.112 and see all the possible CIDR ranges, or enter just a CIDR such as /24.

How do the results help me?

CIDR ranges can sometimes be difficult to figure out just by seeing the proper notation. This tool removes all doubt by doing the calculation for you and displaying the entire range. Useful for administrator who needs to map a subnet.
