My apologizes for not making this clear and thanks for making it understandable. If the user changes NIC the order of the Mac Addresses gets changes, I'm not sure but I also think that are not available to RB if the NIC has been disabled.

Basically using the Mac address of a NIC is not a reliable way to locate a specific computer. In fact to be honest I have no idea of a truly reliable way to do it. I believe Windows XP used 16 different hardware IDs, and it accepted a change of up to 3 at a time or you tripped the activation and it believed it was a different computer.

Things like:
Memory Size and configuration
Hard Drive Serial Number
Graphics Card
Processor
Optical Drive
Bus Speed

and other things that I have forgotten...

Mahalo & Aloha,

Sam Rowlands

Uhhh... the MAC address shouldn't ever change. It isn't reliant on a
connection at all, it's a unique hardware identifier. A device's MAC only changes if it's changed by some spoofing software, or in the rare case of a BIOS configurable onboard. What you all are describing sounds more like
the IP address, which is totally, radically different.

EACH network interface has it's own MAC address, and so if a user
switches from Ethernet to WiFi his computer will be using a different
MAC address.

This is a very old discussion. MAC addresses are considered a poor
choice for license locking.
