Google Last June, CNET disclosed that Google collects and publishes the estimated locations of millions of phones, laptops, and other Wi-Fi devices. All without their owner's knowledge or permission. Google has finally announced how to exclude your home network from this database. Simply append "_nomap" to its name. Details over at CNET. Left unsaid is why the burden is placed on millions of individuals to opt-out, instead of on perpetrator Google.

phoenix,

"MAC addresses have to be unique only within the same broadcast domain (ie, subnet). MAC addresses do not have to be unique on separate subnets, even if within the same building."

Thank you for the response, I already know how they work though. The hardware MAC is designed to be unique globally, even if it's only necessary to be unique locally. It is not a misunderstanding on my part.

To my knowledge we still haven't needed to recycle them in hardware. If you know of a source that talks about manufacturers reusing MACs, I'd love a link.

There appear to be plenty of unassigned entries left scattered throughout.
