    MAC addresses work only when two nodes on a LAN need to transfer data to each other. When your machine needs to send some data to any machine on the Internet, it sends the request to your router; doing so, your machine and the router communicate using their MAC addresses. Then your router uses its MAC address to communicate with the ISP router and so on.

    In order for your website to see visitor's MAC address, you would need to run some program directly on the machine making a request.

    It is possible in Java to obtain your private IP address (the one you use on the LAN). May be it is possible to obtain a MAC address this way as well (that I never tried and can't say for sure, though). See here for an example:

    You have to have Java enabled for this code to work.

    No, MAC addresses are not transmitted to the end user. Just like you can't see the MAC address of a server. Typically only the first hop (router) can see your MAC address, and it does not pass that along with the TCP packet.

    Figured I should also add that if you COULD do it, it would become a huge privacy issue. Sites would start using MAC addresses (which do not change) to track users instead of cookies. :)
