Open a Command Prompt or Terminal window. You can use the arp command on any operating system to determine the MAC address of another computer on the network.

  • On Windows, type cmd in the Windows Search search bar, right-click Command prompt and select Run as administrator .
  • If using macOS, you need to type Terminal in the Spotlight search bar and then double-click Terminal .
  • On Linux, press Ctrl + Alt + T or open a Terminal window from the window manager.

Execute the command ping ipaddress to communicate with the IP address. You need to communicate with the remote computer in order for that computer’s MAC address to be cached—ping is an easy way to do this.

  • If you know the hostname of that computer but don’t have an IP address, simply ping the hostname—the IP address will be returned for you to use in the next step.

Open command prompt. If you can log in to the remote computer with administrator access (and that computer is also running Windows), you can use the getmac command to see all the MAC addresses on this device. [1] Type cmd in the Windows Search search bar, right-click Command prompt and select Run as administrator .

Execute getmac command. The full command would be {{kbd|getmac /s ipaddress /u username /p password .

  • Replace ipaddress with the remote computer’s IP address or hostname.
  • Replace username and password with the remote computer’s administrator username and password.

Find your local IP address. To proceed, you need to know the subnet to scan.

  • Windows: Execute the ipconfig command.
  • macOS: Open System Preferences > Network > Advanced > TCP/IP .
  • Linux: Run the command ifconfig or ip a .

    Execute the nmap command. The full command would be nmap -sn xxx.xxx.xxx.* . Remember to replace xxx.xxx.xxx.* with the network you want to scan. After a few moments, a list of all IP addresses in the network along with their respective MAC addresses will appear.

    • For example, with IP address 10.0.0.3 and you want to scan all hosts in the subnet, use the command nmap -sn 10.0.0.* .

    • Advice

    • You can only find the MAC address of the computer that is in the same subnet of the computer you are using. We cannot determine the MAC address of a computer if we cannot log into that computer remotely.
    • If the computer you are trying to reach is protected by a firewall, it is likely that the MAC address will not be visible.
