About CIDR Calculator
CIDR Calculator is a networking utility to design, partition, and understand subnets. Input an IP address and CIDR prefix length (e.g., /24) to get complete subnet breakdowns.
How to Use CIDR Calculator
- Input the base IP address.
- Select the CIDR prefix (e.g., /24, /16) or subnet mask.
- Review the network details including broadcast address, mask, and IP range.
Frequently Asked Questions
What is CIDR?
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing IP packets, replacing traditional network classes.
What does a /24 subnet mean?
A /24 subnet means the first 24 bits of the IP address represent the network, leaving 8 bits for hosts, which allows 256 IPs (254 usable).
How does it calculate usable IPs?
For any subnet, two IP addresses are reserved: the network address (first IP) and the broadcast address (last IP). Usable IPs = total IPs - 2.
