Fantastic response almut! This is one of the key pieces you have cracked. Once you have an ethernet device to query, this is how get the information using these OID's.

I believe using these OIDs to get the information is better than the other methods of getting the MAC address for a couple of reasons:
1.) It will show you both the currently-being-used MAC address of the device, and the permanent MAC address of the device that is burned into the hardware.
2.) This information is coming directly from the running device driver (Is that true? That is my current understanding).

If that is true, then is it also true that manipulating it is a bit more difficult?

Now, the remaining pieces of the puzzle are, discovering all ethernet devices (even those that are not being used), and discovering which of those are on the motherboard (by that I mean not easily removable).

I'm compiling all the bits of information as they come in, and will post the results, once I have things working the best way for my situation.

Many thanks for all the help
