❓ Frequently Asked Questions
What is the MAC Vendor Lookup used for?
Look up the manufacturer of a network device from its MAC address (OUI).
Is the MAC Vendor Lookup free and private?
Yes — it's free with no sign-up. The MAC Vendor Lookup queries public network services (such as DNS or WHOIS) directly from your browser to fetch live results; IP Ducky never logs or stores what you look up.
Do I need to install anything to use the MAC Vendor Lookup?
No. It works in any modern web browser on desktop, tablet, or phone — no downloads, no browser extensions, and no account required.
