The reason why it does not show your MAC address is that nmap is analysing the traffic it receives. When you talk to a local IP address this does not generate Ethernet frames so it does not involve a MAC address. As such you are expecting nmap to report things it doesn't have access to. You will need to explain what you are trying to achieve and find another tool to do it with. If it's as simple as just wanting to know the MAC address of everything¹ on your broadcast domain, you will just have to look up the MAC of the thing you are doing it from separately. Thanks, Andy ¹ Even then it relies upon the things agreeing to respond, which they might not if they are purposefully hiding. -- https://bitfolk.com/ -- No-nonsense VPS hosting
