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.
It's for wireless enabled purchases at vending machines.
I did an RFP for this in grad school. In our scenario the beverage company was working with AT&T to enable the wireless internet connection.
They'll probably "partner" with other vendors of consumer goods...whatever the marketing people come up with.
Thank you Dave Raggett
They were allocated a single 3-byte OUI, or prefix. When you realize that 16 million OUIs were originally available, it's like making a big deal that a company was granted a /24 IP range.
Coke is rolling out their Freestyle fountain dispensing machines worldwide. Each one has the ability to phone home about inventory levels, maintenance logs, and what drinks are trending where. Coke doesn't do anything small - everything they do is done on a global scale. There are 100,000 - 200,000 fast food restaurants in the United States alone. It doesn't take much imagination to see how that could scale up to 16 million machines worldwide over the product life cycle.
"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."
http://en.wikipedia.org/wiki/MAC_address
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.
That's not what happens. MAC addresses are assigned to vendors that implement products with network hardware, not just the development and manufacture. For example: I can look up any MAC address and see it belonging to Dell, Apple, Linksys, DLink, Netgear, and so on. The first two don't design and fab their own NICs. They use Broadcom, Intel, Marvell, and Realtek chips.
Life is not for the lazy.
What I read: "One of the world's largest companies has need of an allocation unique identifiers for network hardware".
Fuck, they sell 1.7 BILLION coke products every single day (their 2010 annual report, on their website FAQ too).
That means they sell over 1000 products a day for every MAC address they just reserved. They could use them to control the various parts of the fucking production lines via Ethernet and it still wouldn't be enough for their normal, everyday usage of such things. It's certainly no "Internet of things" heap-of-crap headline.
How the hell did this make it onto Slashdot?
It's a 48 bit address space. They have lots of addresses. This is the minimum allocation IEEE hands out. Lot's of companies have a /24 of Mac addresses.

If Slashdot were chemistry it would look like this:Cadaverine
The oldest version of oui.txt I could find is dated 2010. And the allocation was made before that. Which means it has been more than three years since this was news. Anybody know how to look up more precisely, when it was allocated?
Do you care about the security of your wireless mouse?
It's a trademark thing. They just wanted MAC addresses starting with C0:CA:C0:1A.
All I wanted was a cup of tea.
