MAC Vendor Lookup

MAC Vendor Lookup is the fastest way to identify the manufacturer behind any MAC address — fully offline, with no accounts, no tracking, and no ads.

Paste any MAC address and instantly see the vendor, OUI block, registry, and assignment range. The full IEEE OUI database (35,000+ vendors) is bundled with the app and works without an internet connection. Use the camera scanner to read MAC addresses off router labels and device stickers, or paste a wall of text from a log file and let the bulk extractor pull every address it can find.

Made with care in the lab.
