How to find MAC address... either locally or across a network

Getmac | I would like to recommend this parameter "getmac /s \\remotecomputer", it helps you can remote to other PCs easily. While running this command, just wait since it takes a little time and this is the result:,

Returns the media access control (MAC) address and list of network protocols associated with each address for all network cards in each computer, either locally or across a network.
getmac
getmac /v

Note: export the output by using this command getmac /s \\remotecomputer >> c:\getmacresult.txt
