What is MAC Address?
MAC addresses are hardware identifiers for network interfaces. The first 3 bytes (OUI) identify the manufacturer. This tool generates, validates, and looks up MAC addresses.
How it works
We parse the MAC into its OUI and device parts, validate format (dashes, colons, dots), and match the OUI against a local vendor database.
