Coca-Cola Reserves a Massive Range of MAC Addresses
An anonymous reader writes "GNU MacChanger's developer has found by chance that The Coca-Cola company got a range of MAC addresses allocated at the OUI, the IEEE Registration Authority in charge of managing the MAC addresses spectrum. What would Coca-Cola want around 16 million MAC addresses reserved? What are they planning to use them for? Could this part of a strategy around the Internet-of-things concept?"
Vertically integrated vending machines?

If you figure there's one Coke vending machine per 100 people, that's 3 million Coke machines in the US alone. So certainly the scale (if we extend to worldwide) is about right.
"The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. This 48-bit address space contains potentially 2^48 or 281,474,976,710,656 possible MAC addresses."

2^48 / 2^24 = 2^24 so OMG NOES they're getting one-sixteen-millionth of the available space!
If 16 million other companies do this we're TOTALLY SCREWED!
(Unless I did my math wrong or there are other things I'm unaware of, which is totally possible. I'm sure someone who actually knows about networking will either correct me, or confirm that this is a total non-story. If they wanted 16M IPv4 addresses this would be a little different.)
Dear Slashdot: next time you want to mess with the site, add a rich-text editor for comments.
So, Coca-Cola went and spent $665 dollars for a single block. This is not news.
Someone is being clueless- it's not a massive range, it's the smallest range you can reserve.
If you're a large enough corp and it doesn't cost much, you might as well reserve a block for yourself.
I don't see mac addresses going away anytime soon, and since they are given out in blocks of 16 million and there are "only" 16 million blocks one day coca cola's block of 16 million might become handy even if they don't use it now.
