This tool is designed for network administrators, IT technicians and learners, providing the following core functions:
1. Subnetting calculation
- According to the input IP address and subnet mask, automatically calculates Network address, broadcast address, available host range - Support CIDR representation (e.g. /24) and traditional decimal format conversion - Visualization of subnetting results, including host capacity and number of subnets
2. Conversion tool
- Subnet mask in Convert subnet masks between binary (e.g. 11111111.00000000), decimal (e.g. 255.0) and hexadecimal (e.g. FF.00). Instant conversion between IP addresses - IP address conversion, support IPv4 full-format parsing
3. network planning assistance
- Generate Subnetting suggestions， Meet the needs of different sizes of hosts Address conflict detection Provides address conflict detection and reserved address identification Functionality
Usage Scenarios
- Enterprise LAN planning and IP allocation - Configuration verification of network devices (routers, switches) - Teaching of computer network courses and preparation for certification exams (e.g. CCNA/CompTIA).
Operating Instructions: After entering the IP address and mask, the system will generate real-time calculation results. All data are processed in the local browser to ensure privacy and security.
