Network Sleuth: MAC Address Vendor Lookup
Find out exactly what devices are connected to your network by identifying their manufacturer.
What is this tool?
The MAC Address Vendor Lookup tool takes an Organizationally Unique Identifier (OUI)—the first half of a MAC address—and queries an IEEE database to tell you which company manufactured the network card.
Step-by-Step Guide
- Enter MAC Address: Type in the MAC address (e.g.,
00:1A:2B:3C:4D:5E). - Search: Hit the lookup button.
- View Results: The tool will display the vendor name, and sometimes their physical address.
Practical Use Cases
- Network Security: Identify unknown devices connected to your Wi-Fi router.
- IT Administration: Inventory hardware across a corporate network.
- Troubleshooting: Determine the brand of a faulty network interface card.
FAQ
Do you store the MAC addresses I search? No, all searches are performed locally or without logging to ensure your network privacy.
Why is the vendor shown as ‘Unknown’? Modern devices (like iPhones and Androids) use MAC address randomization for privacy, generating fake MACs that don’t belong to any registered vendor.
