    I'm not sure if this is the right forum to place this question is but it's as close as I can find.

    My question is, is there a way to locate the MAC address of a device on a shared network I set up via my MacBook. It would look something like this..

    I'm getting internet via Ethernet to my MacBook, I would then share my internet through the Airport, which is how my Blu-ray player would get internet. I'm trying to find the MAC address of my Blu-ray player.

    I know it seems really weird to do the wireless internet to my Blu-ray how I'm doing it, it's a long story..but is there anyway to view device information on my MacBook of devices that are using my shared internet?

    Thanks for any help!

    Open Terminal and use the arp command with the IP address of the BluRay device, for example:


    arp is used to determine the MAC address behind an IP address or hostname.

    but from my knowledge of MAC addresses, aren't they supposed to be xx:xx:xx:xx:xx:xx, six series of two digit numbers? any thoughts?

    arp drops any preceding zeros, so the MAC is 00:23:08:71:53:68
