Relationship between MAC address and device [closed]

Using a device to find its MAC address is easy, but using a MAC address to find its mother/father (the device which owns the MAC address) is possible? If it is, how?

Notes: I had set up a DoS Protection on my router and it had caught a MAC address into the blacklist. I am not sure how to find the host with the MAC address.

Solution 1:

Your question us a bit unclear, but maybe this will help.

MAC addresses are (meant to be) globally unique per network interface. The first 6 characters (ie 3 bytes) of the MAC address are typically registered to a vendor, and can be looked up. The remaining part AFAIK is unspecofied. (Id say random, only its fairly common to get sequential numbers of cards from the same batch)

It is worth pointing out that its often possible to change/fake a MAC address, so thr lookups to the manuafacturer are a guide only.
