    In my cisco gateway, i can see in the interface that its MAC address is:

    MAC Address: cc:0d:ec:df:c9:87 Internet IP Address: 192.168.0.1 / 24 Subnet Mask: 255.255.255.0

    On my computer, however, if I do arp -a, I get:
    $ arp -a
    gateway (192.168.0.1) at cc:0d:ec:df:c9:84 [ether] on enp3s0

    Can someone please explain this phenomenon? I was worried that I could have been a victim of a MiTM attack.
