Frequently Asked Questions
What format do the MAC addresses use?
Addresses are output in the standard six-octet colon-separated format (e.g., A1:B2:C3:D4:E5:F6). You can also switch to hyphen notation.
Are these valid MAC addresses?
They follow the correct 48-bit hexadecimal format. However, the OUI prefix is randomized and may not map to a real manufacturer.
Can I generate locally administered addresses?
Yes. You can toggle the locally administered bit so the addresses are clearly marked as non-manufacturer-assigned.
