I'm trying to figure out the MAC address of my router.

This picture is of using the command ipconfig:

enter image description here

This picture is of using the arp -a command:

enter image description here

I see it says my IPv4 address is 192.168.1.114, so I go down to it in the arp -a command. However, there are many different MAC addresses for it. It also says the default gateway is 192.168.1.1, so my question is: Which one is my router MAC address? Help would be appreciated. Thanks!

According to your screenshot, the ARP Cache entry for 192.168.1.1 is c8d7.1914.f1d1, which is likely the MAC address of the router interface to which you are connected.

According to your output of ipconfig/all, the MAC Address of your Network Interface is 844b.f522.6f98.

  • Is that the router MAC address?

    Yes. Technically, the result of an ARP response for 192.168.1.1, which is likely your router.

  • Quick question: I did ipconfig /all, and under the one with the IPv4 address set to 192.168.1.114, there is an entry that says "Physical Address: 84-4B-F5-22-6F-98" Is that a router MAC address also?

  • No, that is your MAC address.

  • Well then which one is it? The arp -a one or the ipconfig /all one?

You can issue tracert 8.8.8.8 from your PC and find out the next hop IP address, that would be your next hop (gateway IP address) IP address, after that, issue command arp -a, and see that IP address mapped to which MAC address and that MAC address is the next hop (gateway).

Following is just for example.

C:\Users\>tracert 8.8.8.8  
Tracing route to google-public-dns-a.google.com [8.8.8.8]  
over a maximum of 30 hops:  
  1     5 ms     5 ms     5 ms  192.168.1.1**  
  2     5ms      5ms      5ms   10.11.12.13   
  3  ^C

C:\Users\>arp -a  

Interface: 192.168.1.1 --- 0xb  
  Internet Address      Physical Address      Type  
  192.168.1.1            c8d7.1914.f1d1     dynamic

Hope this answer helps you.

  • I don't have 192.168.1.1 as an interface, but I do have it listed as an internet address as one of them.

Another tool if using Linux is iw for wireless and you can dump the connected router details using: iw dev <device_name> station dump where is obtained from ip a and choose your active wireless name eg: wlp3s0 - this may provide a number of devices, so you'll need to confirm you've identified the correct one. Additionally there is ip neigh show dev wlp3s0 which will provide the AP's connected to your router. Provides the same MAC details
