This tool is designed for network administrators, IT technicians and learners, providing the following core functions:
1. Subnet division calculation
- According to the input IP address and subnet mask, it automatically calculates Network address, broadcast address, available host range - Support CIDR representation (e.g. /24) and the traditional point decimal format conversion - Visual display of subnetting results, including host capacity and the 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 resolution.
3. network planning assistance
- Generate Subnetting suggestions， Meet the needs of hosts of different sizes Address conflict detection and reserved address identification Functions
Scenarios
- Enterprise LAN planning and IP allocation - Configuration verification of network devices (routers, switches) - Teaching 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.
