## What is 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.

FEATURES

• Instant offline lookup — no network calls, no waiting
• Bundled IEEE OUI database, fully up to date
• Camera scanner with on-device OCR
• Bulk extraction from pasted text, logs, or imported files
• History with notes, tags, and favorites
• Insights view summarizing your most-seen vendors
• Home-screen widget for recent lookups
• Share Sheet extension — extract MACs from any app
• Shortcuts & App Intents — automate lookups from anywhere on iOS
• iPad and iPhone, light and dark mode, full Dynamic Type and VoiceOver

PRIVACY

This app is fully offline. No accounts. No analytics. No tracking. No third-party SDKs. Your lookups, notes, and tags never leave your device.

TIP JAR

The app is free. If it earns its keep on your home lab, network closet, or pen-test rig, an optional tip is appreciated. Tips unlock nothing — everything in the app is already yours.

Made with care in the lab.
