📖 How to Find MAC Vendor – Step by Step
- Step 1: Enter a MAC address (e.g., 00:1A:2B:3C:4D:5E or 001A2B3C4D5E).
- Step 2: Click “Lookup Vendor” – the tool normalizes the address and extracts the OUI (first 6 hex digits).
- Step 3: The tool queries the public macvendors.com API to find the manufacturer.
- Step 4: The vendor name is displayed along with the formatted MAC and OUI.
- Step 5: Use this information to identify network devices or troubleshoot hardware.
💡 What is a MAC Address OUI?
- ✔️ OUI (Organizationally Unique Identifier) is the first 3 bytes (6 hex digits) of a MAC address.
- ✔️ It uniquely identifies the hardware manufacturer registered with IEEE.
- ✔️ Use this tool to verify network devices or detect unknown hardware on your network.
- ✔️ 100% client‑side – your MAC addresses are never stored or logged.
💡 Pro Tip: MAC addresses can be spoofed, but the OUI usually reveals the original manufacturer. Works for Ethernet, Wi-Fi, Bluetooth, and other network interfaces.
