Nobody can see your MAC address on the Internet. Only a pc on the same LAN as yours can see your MAC address,includes people sharing WiFi with you.
The MAC-address is part of the OSI Network Model. It's only used for communication in your local network, be it cabled or wireless.
MAC definitely gets lost is when it passes your router, the router only transmits the IP packet to "the Internet".
When connecting to the internet your router will not use your computers, but its own MAC address to forward the packets.
This switchy bit happens on all routing points, so your ISP will take your packet get the IP packet out and put it into another MAC packet and so on.
If you are using IPv6 it might be possible that your IP Address can be generated using parts of your computers MAC address and then its feasible.
Disable IPv6 if you feel paranoid.
If you read about NSA spying on us folk then its the help of the Embedded chip manufactures and ISP's and software O/S producers that pass on and allow undetectable 3 party access to our communications.
Did anyone read about " smart bins" in London streets that detect your Smartphone when you get close the bins read your smartphone data and provide a customise advert that runs on the LCD side panels when you pass it?
So if you were say looking for a Caribbean cruise on your smartphone the bin would know and show you an advert related....hehehe all without the users consent! or knowledge.
Personally I dont use smartphones/I-phones/Tablets especially with Android or Apple O/S for very reasons stated from day 1 that they were on sale.
Anything Linux pisses NSA off! and anyone else looking to creep into your private world :-)
I was in high level data comms for routing internet and encrypted data over satellite and terrestrial networks is how I know about MAC.
We used the VBI for transporting if any techies are interested how.
yep simple no overload on signal when carried.
