Re: MAC address is(n't) untraceable (Score 1)

A mac address alone is still as close to worthless as it's possible to get ...

A MAC address on a random wireless connection in a carpark is probably worthless. A MAC address at an organization running a "real" DHCP server (ISC et al) gets you the PC's Windows hostname out of the DHCP log files, and it gets you a current IP address and a switch CAM table trace if the MAC ever comes back.

We do this all the time (after first searching logs for IP -> MAC) to try to locate and notify impacted users when processing DMCA takedown notices, which typically come with an (alleged) offense date some time in the past.
