CIDR Calculator

Estimator

Calculate CIDR ranges, convert between CIDR and subnet masks.

About This Tool

CIDR notation (e.g., 10.0.0.0/8) combines the network address with the prefix length. /32 is a single host; /0 represents the entire Internet. Cloud providers like AWS and Azure use CIDR to define VPC subnets.
