Subnet Suite

A feature-rich .NET web application for network calculations.

SubnetSuite is a feature-rich, .NET-based web application that provides tools for subnetting, VLSM design, supernetting, binary math, IPv6 calculations, and visual network planning.

🛠️ Features

🌐 Subnet Calculator

• Supports both CIDR and dotted-decimal input
• Displays subnet mask, wildcard mask, broadcast, host range, and binary breakdown

📐 VLSM Calculator

• Accepts multiple subnets with host requirements
• Calculates network ranges using Variable Length Subnet Masking
• Exports results to CSV
• Optional subnet labeling

🎯 Supernet Calculator

• Aggregates multiple CIDRs into a single supernet
• Supports two modes: smallest supernet or minimal CIDR blocks

🖥 VLSM Visualizer

• Drag-and-drop interface for routers, switches, PCs, servers, etc.
• Connect devices with cables and auto-generate subnets
• CSV export and IPs auto-assigned visually

📊 Binary Calculator

• Add or subtract binary numbers
• View result in both binary and decimal

🔁 Binary/Decimal/Hex Converter

• Instant conversion between formats

🧮 IPv6 Calculator

• Expands and compresses IPv6 addresses
• Calculates usable range and subnet allocations

📈 Uptime Monitoring (Internal)

• Powered by Uptime Kuma
• Monitors availability and service health

🚀 Deployment & CI/CD

The app is deployed on a Windows Server 2022 using:

• .NET 8.0
• GitHub Actions CI/CD with a self-hosted runner
• Cloudflare Tunnel exposing localhost to subnetsuite.com
• Auto-restart using a Windows service or script

Workflow Summary:

1. Push to main
2. GitHub runner pulls latest commit
3. Publishes app to C:\Published\SubnetSuite
4. App is restarted and served on localhost:5000
