yes they do, what reason would you need it though out of curiosity 

I'm wondering this for two reasons: 1 - as the MAC address is unique, we would have a way to prevent and find a stolen unit (if the serial number not shown) 2 - free access to a network wirelless (I'm developing with my CDJ and DJM).

good thinking actually on the stolen part, I will have to let a Pio rep though answer where it is, not sure what info they will allow on the forum, it is accessible though, I will tell you that much

I found a Windows command that solves the problem:

The command is: "Arp -a".

To use this program is necessary that the CDJ and DJM communicate with your computer with Windows installed.

I run the rekordbox.

I clicked on LINK (to be shown the devices).

After this I run the command "Arp -a" in the Windows command prompt.

With this command will show a listing of all interfaces and their MAC addresses.

You can connect one device at a time in rekordbox to know exactly which address corresponds to the equipment.

The address of Pioneer equipment have the following pattern: 169.254.x.x

My results:

CDJ 1 (Left):

- IP: 169.254.173.77

- MAC: 00:E0:36:BF:AD:4D

CDJ 2 (Right):

- IP: 169.254.173.155

- MAC: 00:E0:36:BF:AD:9B

DJM 2000:

- IP: 169.254.15.64

- MAC: 00:E0:36:D2:0F:40

Post the results you get here.

Thanks.

If your Pioneer equipment is networked and connected to a network with a router or access point, then logging into the router or access point will enable you to view the IP and MAC addresses of your hardware.

thats an interesting idea too for people in another thread wondering if they can code the s/n into the hardware, now they can just record their MAC address pretty easily
