How do I identify an unknown device on my network? ›

Using free MAC address lookup tools, someone can track down your device's vendor and potentially identify what type of device it is and the time period it was produced in. These details are encoded in the first six digits of the MAC address — its Organizational Unique Identifier.

A WHOIS lookup tool allows you to query the contact information associated with an IP address. For a safe, reliable way to look up an IP address, you can use the IP lookup tool on whatismyipaddress.com. Simply paste the IP address into the lookup box and you'll get a results page with info about that IP address.

To identify an unknown device, go to your device manager (you can find it by right clicking the Start button). Look for the yellow triangle with an exclamation mark.

Using the IP addresses, you can ping it to find the Mac Addresses of the connected devices by sending an ARP Message. Type “Arp-a,” and a list of all the connected devices with their MAC addresses will be available.

An IP address is simply a numeric tag that identifies your device and provides information about your general geolocation.

Both MAC addresses and IP addresses serve the same purpose, which is to identify a device on a network. While the MAC address identifies the physical address of a device on the same local network, the IP address identifies the device globally or through its internet address.

IP Address (Internet Protocol address): Also, known as the Logical Address, is the network address of the system across the network.
