Wireless networks exist in many homes and are often combined with wired devices connected directly to a router. While physically locating your local area network's wired devices is simple; wireless devices often remain hidden. However, using the Windows' command-line interface to determine all IP addresses provides a virtual view of all wired and wireless devices that are, perhaps unknowingly, accessing your home network. On the other hand, if you have access to your router's administration page, then you can also view all assigned network IP addresses through the router's admin settings.


Using Router Administration Access

Step 1

Log in to the router using your administrator credentials.

Step 2

In the majority of commercial routers, click the "Status" tab, then click the "Local Network" option.

Step 3

Click the option to view the "DHCP Clients Table." A new window appears listing all local network connections with IP addresses.


You can save your output file from the command-line interface to any name and location you desire. Simply change the “c:\lanipaddresses.txt” to a different hard drive and location. No matter the name, ensure you place “.txt” as the file extension or you won’t be able to view the report.

If you are not sure of the IP address of your router, then obtain it by typing “ipconfig” at the Windows’ command prompt. The IP address of your router is listed as the “Default Gateway.”

If you own a router lacking the “Status” page in the administration menu, then check the device's online documentation to determine how to view the “DHCP Clients Table,” which when accessed will indicate all IP addresses on the LAN.
