Calculate IP subnets, CIDR notation, network ranges, and subnet masks
1. Enter IP Address: Input any valid IPv4 address (e.g., 192.168.1.1)
2. Enter CIDR: Specify the subnet size using CIDR notation (0-32)
3. View Results: Get detailed subnet information including network address, broadcast address, and host range
4. Split Subnets: Use the subnet splitting feature to divide your network into smaller subnets
5. Recursive Splitting: Further split individual subnets by clicking the split button on each subnet
6. Auto-Update: Split subnets automatically update when you change the IP address or CIDR notation
7. Export Data: Download complete subnet data (main subnet + all splits) as a single CSV file
