MAC Address Question
 

If I am surfing a website or posting to a website, can that website (server etc.) see the MAC address that I am using?

not normally, unless you have some sort of script/plugin/software on your computer that is sending that information

Thanks...
But I am still a little uncertain.

I doubt it, but if you unsure use a firewall and vpn

Yes - based on your IP

Only thing I could think about is geolocation but after some research even this is not possible.

Maybe Big Brother Google can help you.

For a LAN-network I can understand that this program can get your MAC-address by IP.
But a website on a server over the internet ?

Ahhh - I take back what I said :) Don't know what I am thinking this morning.

misterhhs is correct - You can not get MAC address if you are not on the same LAN

There is no way to get your MAC address over the internet

So, is there a ban a mac address and not an IP address? So if the IP changes the mac address stays the same correct?

A MAC-address stays the same for the whole lifetime of this device. Even a refrigerator that can contact automatically the manufacturer when their is a failure has a MAC-address.

Correct although it is possible to spoof a MAC address if required.

Physical MAC addresses are permanent by design, however there are ways to spoof your MAC address to make it look different.

:2 cents:

even better - you need no Mac for a MACadress

Correct :pimp
