How to read the result

A MAC is 6 bytes (12 hex digits). Separators are cosmetic: colons, hyphens, Cisco dots, or plain hex all encode the same bytes. Bit 0 of the first byte = unicast/multicast, bit 1 = universal/local.

Example

00:1B:44:11:3A:B7 → 001B.4411.3AB7, 00-1B-44-11-3A-B7

FAQ

Which formats are shown?

Uppercase colon, lowercase colon, hyphen, Cisco dotted, and plain hex — plus the OUI (first 3 bytes).

What is unicast vs multicast?

Bit 0 of the first byte decides: even = unicast, odd = multicast (e.g. FF:FF:FF:FF:FF:FF broadcast).
