Frequently Asked Questions

Find answers to common questions about this tool.

What MAC address formats can I generate?

Standard (XX:XX:XX:XX:XX:XX), Cisco (XXXX.XXXX.XXXX), bare hex (XXXXXXXXXXXX), and vendor-prefixed format.

Can I specify the OUI (vendor prefix)?

Yes. Enter a 6-character OUI prefix (like "00:1A:2B"). The remaining 6 hex digits are randomly generated. Common vendors are available as presets.

Are the MAC addresses generated with real vendor OUIs?

Random MACs use any valid hex combination. View "List Vendors" to see registered OUIs and generate MACs with real vendor prefixes.

Can I generate multiple MACs at once for testing?

Yes. Set the count up to 100. Each MAC is unique and randomly generated.

Does the tool validate a MAC address I paste in?

Yes. Paste any MAC address and the tool validates its format, checks if the OUI matches a known vendor, and shows the vendor name.
