MAC Address Tools (Format, Vendor Lookup)

Parse and normalise MAC addresses in any common format (aa:bb:cc:dd:ee:ff, aa-bb-cc-dd-ee-ff, aabb.ccdd.eeff, aabbccddeeff). Decode the multicast and locally-administered bits. Look up the OUI (Organisationally Unique Identifier) against the most common vendor prefixes.

How to use the MAC Address Tools (Format, Vendor Lookup)

Paste a MAC address in any format. The tool normalises it to canonical aa:bb:cc:dd:ee:ff form, then breaks it down: OUI (first 3 bytes = manufacturer ID), unicast/multicast bit, globally/locally administered bit, and possible vendor name.
