⚙️ Network Configuration

Most users won't need to edit anything - the tool auto-detects your network. But if network scanning doesn't find devices, you may need to adjust these lines:

📍 Location: main.cpp around line 450-460

// In the scanNetwork() function - edit if needed:

if (localIP.startsWith("172.16.")) {
    networkRange = "172.16.0.0/23";  // ← Change this number if needed
} else if (localIP.startsWith("192.168.")) {
    QStringList parts = localIP.split('.');
    networkRange = parts[0] + "." + parts[1] + "." + parts[2] + ".0/24";  // ← Usually fine
} else if (localIP.startsWith("10.")) {
    networkRange = "10.0.0.0/8";     // ← Change this number if needed
} else {
    // Fallback for other networks
    QStringList parts = localIP.split('.');
    networkRange = parts[0] + "." + parts[1] + "." + parts[2] + ".0/24";
}

🔍 How to Check Your Network:

ip route | grep default

📝 Only Edit If:

• Network scan finds 0 devices but you know there are devices You're on a corporate network with custom IP ranges Your router uses non-standard subnets

Requirements

• Qt 6.0+ - Modern C++ GUI framework
• libpcap - Low-level packet capture
