NetScan

About this app

NetScan is a powerful network intelligence app for Android that gives you complete visibility into your local network — no root required.

NETWORK SCANNER
Discover every device on your WiFi network in seconds. See IP addresses, MAC addresses, device names, manufacturers, OS guesses, and HTTP page titles — all updated in real time as devices are found.

PORT SCANNER
Run TCP and UDP port scans against any host. Detect open services (HTTP, SSH, RDP, MySQL, VNC and more), grab service banners, and inspect TLS certificates on HTTPS ports.

SECURITY TOOLS
• ARP spoof detection — alerts when a device claims multiple MAC addresses
• Port change detection — notifies you when open ports change between scans
• Real-time monitor mode — continuously rescans your network at set intervals
• Background alerts — get notified when unknown devices join your network

NETWORK TOOLS
• Traceroute with RTT per hop
• Ping with loss and average RTT stats
• DNS forward and reverse lookup
• Wake-on-LAN magic packet sender
• Subnet calculator (CIDR notation)
• mDNS / Bonjour service browser
• SNMP query for device info
• IPv6 neighbor discovery
• HTTP endpoint prober

HISTORY & EXPORT
Every scan is saved. Export results as CSV or JSON to your Downloads folder.

DESIGNED FOR
Network administrators, IT professionals, developers, and anyone who wants to know what's on their home or office network.

All scanning targets your own local network only. No data leaves your device.

What’s new

Tap-to-run tools from Home

Tool shortcuts on the Home screen now do what they say. Tapping
Ping, Traceroute, DNS Lookup, DNS Benchmark, mDNS Browser, Subnet
Calc, SNMP Query, IPv6 Scan, HTTP Prober, IP Conflict Detector,
ARP Spoof Detector, or Bandwidth Test takes you straight to that
tool and starts it — no more scrolling and tapping again.

Inputs are prefilled from your network:
Ping / Traceroute / SNMP / HTTP Prober: Gateway
Subnet Calc : your /24
Guest Net Scanner: an adjacent /24
