MAC Address Lookup & Vendor Checker

How to use MAC Address Lookup & Vendor Checker

Enter a full 12-digit MAC or a six-digit OUI, with optional colon, hyphen, dot or space separators. Public unicast assignments are queried through MACLookup; local and multicast bits are explained without guessing a manufacturer. Vendor assignment does not establish device model, owner or authenticity.
