How to Scan All Connected Devices on Your Local Network in Windows 11 & 10

Futomi Hatano Updated August 2026 4 min read Windows 11 & 10

With dozens of Wi-Fi smart plugs, smart TVs, security cameras, phones, laptops, and NAS storage units connected to your home or office router, identifying which IP address belongs to which device can be tedious. Here is how to perform a fast, complete scan of your local network on Windows.

Why Traditional Command Line Tools Fall Short

Windows provides commands like arp -a or ping. However:

  • arp -a only shows devices your PC has recently talked to, missing idle smart home sensors.
  • Manual pinging of 254 addresses in PowerShell is slow and lacks device vendor resolution.
  • Router admin web pages are often clunky and slow to refresh.

Fast GUI Network Discovery with fTool Home Network Probe Pro

fTool Home Network Probe Pro scans your entire subnet in seconds using multi-threaded asynchronous ICMP and ARP sweeps, resolving manufacturer names from official IEEE MAC OUI databases.

1

Select Your Network Adapter

Choose your active Wi-Fi or Gigabit Ethernet connection. The app automatically determines your subnet range (e.g. 192.168.1.1 - 192.168.1.254).

2

Run High-Speed Sweep

Click Start Scan. In 2 to 5 seconds, all live hosts are mapped with IP address, round-trip latency (ping), MAC address, and vendor manufacturer name (e.g., Apple, Sony, TP-Link, Espressif).

3

Inspect Open Ports & Services

Click on any detected host to run a quick port scan (HTTP 80, HTTPS 443, SSH 22, SMB 445, RTSP 554, RDP 3389) to identify network cameras, file shares, or web administration panels.
