🖧 MAC Address Vendor Lookup

What is a MAC Address?

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.

How Does MAC Lookup Work?

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.
