A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications on the physical network segment. It's a 48-bit address typically displayed as six groups of two hexadecimal digits.
The first three octets (or six hexadecimal digits) of a MAC address represent the Organizationally Unique Identifier (OUI), which identifies the manufacturer of the network device. Our tool queries this OUI prefix to determine the vendor.
00:1A:2B:3C:4D:5E00-1A-2B-3C-4D-5E001A.2B3C.4D5E001A2B3C4D5EMAC Vendor Lookup is a free online tool that identifies the manufacturer of a network device from its MAC address. The first three bytes (OUI - Organizationally Unique Identifier) of a MAC address are assigned to manufacturers by IEEE, allowing identification of the device maker.
This tool is useful for network administrators to identify unknown devices, security professionals to detect rogue hardware, and anyone curious about the devices on their network.
Identify the manufacturer of any network device from its MAC address.
Access comprehensive IEEE OUI database with millions of registered vendors.
Identify unknown devices on your network for security auditing.
Accept MAC addresses in any format: colons, dashes, or no separators.
A MAC (Media Access Control) address is a unique 48-bit identifier assigned to network interface cards. It consists of 6 pairs of hexadecimal digits, like 00:1A:2B:3C:4D:5E. The first 3 pairs identify the manufacturer.
On Windows, run "ipconfig /all" in Command Prompt. On Mac, check System Preferences > Network > Advanced. On Linux, use "ip link" or "ifconfig" commands. On phones, check network settings.
OUI (Organizationally Unique Identifier) is the first 3 bytes of a MAC address assigned by IEEE to manufacturers. It uniquely identifies the organization that created the network device.
