NetScope: LAN Scanner

NetScope is a focused network diagnostics app that helps you understand and troubleshoot your Wi-Fi or Ethernet network.
Use the live subnet scanner to see which devices are responding, compare response times, and check commonly used TCP services. The built-in toolkit provides practical measurements without accounts, advertising, analytics, or cloud storage.
Features:
• Scan devices responding on your local network
• Visualize scan coverage with a live subnet grid
• Review device IP addresses and response times
• Check common TCP ports and services
• Measure connectivity using four-sample ping
• Resolve hostnames and IP addresses with DNS lookup
• Calculate IPv4 subnet masks, boundaries, and usable ranges
• Use light and dark instrument themes
Privacy by design:
NetScope processes diagnostic results on your device. It does not collect or upload network addresses, port results, DNS answers, or usage data.
Only scan networks and devices you own or are authorized to diagnose.
