MACAdr

MACAdr is a command-line application that you can use to quickly identify the MAC address of your own computer and other ones in the local network. It also displays vendor information.

Setting up this MAC address finder isn't necessary. It's packed in a just one .exe that can be accessed from any part of the hard drive or directly from a thumb drive. Administrative rights aren't required, and there are no software prerequisites involved to get this tool to work.

After opening a Command Prompt window, you can call MACAdr's process by just writing its file name and extension. Doing this without any arguments instructs the program to obtain the MAC address of your workstation for each network interface, such as Ethernet, wireless LAN or tunnel adapter.

The syntax is MACAdr.exe [[network] | [host] | [MAC]] [/s:x], which can be shown in the CMD window using /? or /h. "network" represents the network address you want to get the MAC address from, "host" is the name or local IP address of the remote computer whose MAC address you want to obtain, and "MAC" is the MAC address of the PC if you want to know vendor information.

Just one of these three arguments can be entered at a time when executing a command. You can indicate the separator you want to use (/s:x, the default one is space).

Other aspects worth mentioning are that MAC addresses can be written in complete (xx.xx.xx.xx.xx.xx) or short form (xx.xx.xx) while network addresses must be specified with the three octets and the dot after the last octet (e.g. 192.168.0.).

All aspects considered, MACAdr provides users with a fast way of identifying the MAC addresses of their own computers as well as remote ones in the local network, in addition to vendor info. It had minimal impact on computer performance in our tests and worked smoothly on Windows 10.
