How to determine the mac address of a laptop (on a network card for a cable and on a network card for wi-fi)?

Question

Network administration

Hello. How to determine the mac address of a laptop (on a network card for a cable and on a network card for wi-fi). I set up access to the Internet (via wi-fi) at mac addresses - that's why I'm asking? By cable, the Internet works for all clients without filtering by mac addresses. I know that mine has at least 2 Mac addresses: for a network card for cable and for a network card for wifi.

Answer 1

ipconfig /all for Windows
ifconfig -a for nix

Answer 2

ipconfig /all will show both. You can look at the DHCP server log, if there is one.
