If you've run into hardware addresses that shouldn't exist, you should know that imq uses these bogus mac addresses.
On a related note, you can check which vendor produces an equipment based on the first three shorts of the mac address; i.e. "00:17:f2" is produced by Apple. Mac-to-vendor mapping online here.
