I am having some issues at work and there is a new network admin in place. I think I am being monitored so decided to run ArpSpy X in two scenarios:
- Over WiFi bridge plugged into Cisco router to took a note of the router IP and MAC address. Then I did a vendor look up and it shows as a Cisco router (which it should) but I also have another Mac entry for the same IP (the router IP) of
- Then through Hardwired via Ethernet I only see the
FF:FF....address for the router IP.
At the moment I only use the network via VPN (OpenVPN) to an external VPN provider to be safe.
Can someone please tell me if the double MAC address via wired and the single
FF:FF:FF.... is normal or am I just being paranoid?
