Thanks for all the replies, it has given me a lot to think about. I was just interested in taking any MAC (spoofed or not) and trying to extract as much information as possible from it. Including possibly checking to see if it is legit or not. The reasoning behind my project is as follows: I lived in a college community and regularly have people trying to connect to my wifi network. I regularly check my network for new devices trying to see who/what is trying to connect. I know how to white/black list and do as necessary. But I like to know what is trying to connect. I know tools out there exist that can do this for me, but I wanted to work on my programming some and figure this would be a nice project.

As the title says I'm tinkering with Mac Addresses. I'm writing a simple python script that just takes in a Mac Address as a string and tries to figure out as much information about the device given nothing but that address (not even network access). However, I'm not sure what all that Mac can tell me or how to determine it. I know Mac Addresses can be spoofed. I know that the first 3 octets usually represent the OUI (Organizational Unique Identifier) but beyond that what can a Mac Address tell me? What other useful information can I extract? (any details or resources about how would be nice too) Thanks in advance.
