Core Functions: - Automatic subnetting： Input IP address and mask digits to automatically calculate the available subnet range, broadcast address and number of hosts. -Conversion Convert subnet masks to decimal.： Supports bi-directional conversion of subnet masks between decimal (e.g. 255.255.255.0) and binary (e.g. 11111111.11111111.11111111.00000000). - CIDR/VLSM support： Flexible handling of Classless Inter-Domain Routing (CIDR) and Variable Length Subnet Mask (VLSM) planning requirements. -CIDR/VLSM support IP Address Tool： Includes decimal, hexadecimal and binary conversion of IP addresses.
Usage
1. Basic Calculation： Fill in the input box with the destination IP address (e.g. 192.168.1.0), select the number of mask digits (e.g. 24) or enter the mask directly. 2. Advanced operation： Click the "Convert" button to get subnet details, including available IP ranges, network addresses and capacity of each subnet. 3. Export Results： Copy the calculation results or generate a PDF report for easy archiving of network planning documents.
Scenarios
- Enterprise LAN planning and IP address allocation - Exam preparation for network certification exams (e.g. CCNA/HCIA) - Subnet configuration in data center virtualization environments - Network address management for Internet of Things (IoT) devices Tool Advantages: No need to install, completely free, responsive design adapted to the computer / cell phone, real-time calculations with zero delay.
