Get Router MAC Address with CCGetMAC

Router MAC address

MAC is acronym for for Media Access Control address. It is a unique identifier attached to almost most all networking equipment such as Routers, Ethernet cards and other devices.

If you do not have access to router admin interface (via telnet or webbased), use following method to find out router MAC address. You need to use arp command (available on both Windows, Linux/Unixish systems).

ARP manipulates the kernel's ARP cache in various ways. The primary options are clearing an address mapping entry and manually setting up one. For debugging purposes, the arp program also allows a complete dump of the ARP cache.
ARP shows the entries of the specified hosts. If the hostname parameter is not used, all entries will be displayed.

Task: Find out router Mac Address

To get your router MAC address, use arp command as follows:

$ /usr/sbin/arp -a
OR
$ arp -a

Output:
router (192.168.1.254) at 00:08:5C:00:00:01 [ether] on eth0
fbsd6 (192.168.1.16) at 00:0F:EA:91:04:07 [ether] on eth0

In above example 00:08:5C:00:00:01 is MAC address of my router. If you cannot find MAC address then just ping to your router once (my router had 192.168.1.254 IP)

$ ping 192.168.1.254

And then run (type arp -a) above arp command again. If you have telnet access to router then you can just telnet into router and find out MAC address:

$ telnet 192.168.1.254

Output:
Welcome to nixCraft Router!
Login: admin
Password:

Once logged in type ifconfig command:

$ ifconfig br0

Output:
br0 Link encap:Ethernet HWaddr 00:08:5C:00:00:01
inet addr:192.168.1.254 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:0
RX bytes:9146189 (8.7 MiB) TX bytes:74456679 (71.0 MiB)

Please note that your interface name (br0) could be different. You can also use ifconfig -a command.
