Get-WmiObject Win32_NetworkAdapterConfiguration | 
    Where-Object { $_.IPEnabled -eq $true }
```

### 3. Manufacturing Configuration Detection
```powershell
Get-ShopfloorConfig     # DNC and GE registry analysis
Get-GERegistryInfo      # Architecture and DualPath detection
```

### 4. Data Aggregation & Transmission
```powershell
# Combine all data sources
$postData = @{} + $systemInfo + $networkInfo + $manufacturingInfo

# Send to dashboard API
Invoke-RestMethod -Uri $apiEndpoint -Method POST -Body $postData
```
