IP Calc Network

IP addressing and subnetting calculator, ideal for network professionals or anyone wanting to learn more about IP networks.

Features

IP Calculation

• Comprehensive IPv4 address calculation with network, broadcast, and valid host ranges
• Full CIDR support (/1 to /32) with automatic decimal mask conversion
• Subnet mask display in both decimal (e.g., 255.255.255.0) and binary formats (e.g., 11111111 11111111 11111111 00000000)
• Detailed binary representation of IP addresses with space-separated octets for improved readability
• Automatic calculation of available hosts in each subnet
• Network address calculation and display in both decimal and binary formats
• Visual representation of subnet masking operations

Network Tools

• Ping functionality to verify connectivity with remote hosts
• Port scanning for network service diagnostics
• IP range scanning to discover active hosts in a subnet
• IP range calculation for network management
• History tracking of ping and port scan operations
• Common ports quick-selection for faster scanning

Subnet Management

• Automatic subnet generation based on the desired number of subnets
• CIDR-based subnet division with optimized address space allocation
• Calculation of first and last valid host in each subnet
• Quick visualization of subnet distribution
• Network ID and broadcast address calculation for each subnet

Interface and Usability

• Multi-language interface:
  • Portuguese 🇵🇹
  • English 🇬🇧
  • French 🇫🇷
  • German 🇩🇪
• Automatic light/dark theme detection based on system preference
• Modern, responsive design using Material-UI components
• Intuitive interface with explanatory tooltips
• Tab-based navigation for better organization of tools
• Real-time calculation and updates when changing CIDR values

Technologies

• React 18 with functional components and Hooks for state management
• TypeScript for static typing and enhanced development experience
• Material-UI v5 for components, theming, and responsive design
• i18next for internationalization and multi-language support
• Pure JavaScript/TypeScript implementations of network calculation algorithms
• Efficient state management with React hooks (useState, useEffect, useCallback)

Installation

# Clone the repository
git clone https://github.com/seu-usuario/ipcalc-network.git
cd ipcalc-network

# Install dependencies
npm install

# Start the development server
npm start

Usage

Development Mode

npm start

This runs the app in development mode. Open http://localhost:3000 to view it in your browser. The page will automatically reload when you make changes to the code.

Testing

npm test

Launches the test runner in interactive watch mode. See the running tests documentation for more information.

Production Build

npm run build

Builds the app for production to the build folder. It bundles React in production mode and optimizes the build for best performance. The build is minified and filenames include content hashes for efficient caching.

Key Features in Detail

Binary Representations

• Binary IP address: View any IPv4 address in binary format with spaces between octets
• Binary subnet mask: Visualize subnet masks in binary to better understand network division
• Binary network address: See how the network address is derived using binary operations

Network Analysis Tools

• Active host detection using ping-like functionality
• Common service detection with port scanning
• Network range visualization and management
• Interactive CIDR slider for subnet adjustments

Responsive Design

• Works on desktop, tablet, and mobile devices
• Optimized layouts for different screen sizes
• Accessible interface with keyboard navigation support
