Welcome to the IP Calculator App, a sophisticated web-based tool designed to simplify network calculations for IT professionals, students, and technology enthusiasts. This application provides an intuitive interface for performing complex IP subnet calculations with precision and efficiency, eliminating the need for manual computations or command-line tools. Whether you're designing a new network infrastructure, troubleshooting connectivity issues, or studying for certification exams, our calculator delivers instant, accurate results in an accessible visual format that enhances understanding of networking concepts.

Built with modern web technologies including HTML5, CSS3, and vanilla JavaScript, the IP Calculator offers a responsive, cross-platform experience without requiring any installations or dependencies. The application features a clean, dual-theme interface that adapts to your preference with both light and dark modes, comprehensive validation to prevent input errors, and visual representations of subnet structures that make abstract networking concepts tangible. With support for both traditional subnet mask notation and CIDR format, plus example configurations for common network classes, this tool provides everything you need to streamline your networking workflow in one convenient package.
