🧮 CIDR IP Calculator
Enter an IP address with CIDR notation (e.g., 192.168.1.0/24) to get the range, mask, number of hosts, and other useful network info.
What Is CIDR and How This IP Calculator Works
CIDR (Classless Inter-Domain Routing) is a method for assigning IP addresses and routing IP packets. For example, 192.168.0.0/24 means the first 24 bits are the network part.
Our calculator helps you determine:
- 🎯 Subnet mask
- 📍 IP address range
- 🔁 Number of usable hosts
- 📤 Broadcast address
This tool is useful for network setup, hosting, and server administration. All calculations are done in your browser — no data is sent to the server.
