Identify the manufacturer (vendor) of any device using its MAC address or OUI.
Our MAC Address Lookup Tool (also known as an OUI Lookup) allows you to identify the manufacturer of a network device using its physical MAC address. Every network interface card (NIC) has a unique Media Access Control (MAC) address assigned by the manufacturer. The first 6 characters of this address (the Organizationally Unique Identifier or OUI) are registered to a specific vendor (like Apple, Cisco, Intel, or Dell). This tool queries the IEEE OUI database to instantly reveal who manufactured the device.

Identify unknown devices on your Wi-Fi network, inventory hardware, and detect rogue access points.
Analyze router logs to identify intruder device types and verify legitimate hardware in secure zones.
Find out what "Unknown Device" is connected to your router and identify smart home gadgets.
We don't log or store any IP addresses or search queries. Your privacy is hard-coded into our architecture.

A MAC (Media Access Control) address is a unique hardware identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. It is often referred to as a physical address or hardware address. It typically looks like `00:1A:2B:3C:4D:5E`.
OUI stands for "Organizationally Unique Identifier". It refers to the first 24 bits (first 6 characters) of a MAC address. This prefix is purchased by manufacturers from the IEEE and uniquely identifies the company that built the device (e.g., `00:03:93` belongs to Apple).
No. Unlike IP addresses, MAC addresses do not contain geographical location data. They only identify the manufacturer of the hardware. However, large databases of Wi-Fi router MACs (BSSIDs) linked to GPS coordinates are used by services like Google Maps to improve location accuracy, but this data is not publicly available via standard OUI lookups.
Modern smartphones (iPhone iOS 14+ and Android 10+) use "MAC Randomization" for privacy. When they connect to a Wi-Fi network, they generate a fake, random MAC address instead of using their real hardware address. This prevents retailers and trackers from building a history of your movements across different Wi-Fi networks.
On Windows: Open Command Prompt and type `ipconfig /all`. Look for "Physical Address". On macOS: Go to System Settings > Network > Wi-Fi > Details > Hardware. On iPhone: Settings > Wi-Fi > Tap the (i) next to your network. On Android: Settings > About Phone > Status information.
