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?"
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.
Don't forget that a MAC address is 48 bits. The vendor ID portion is 24 bits - leaving 24 bits (approx. 16 million addresses) as the smallest range of addresses you can obtain if you obtain a single VID.

Never been to a strip club, but I did a quick google search and found a couple of threads on the subject.
Two answers stood out - 1, some clubs issue coupons that you can use in place of money; the strippers just redeem them at the end of the shift. 2, use $5s, you goddamn cheapskate. :)
