FAQ

What is the structure of a standard 48-bit MAC address?

A standard MAC comprises six octets (48 bits). The first three octets represent the vendor OUI, while the final three octets represent a unique device ID.

What is a Locally Administered MAC address?

Setting the second least-significant bit of the first octet designates the MAC as locally assigned, ensuring no conflict with globally registered factory OUIs.

Can I choose between colon, hyphen, and dot formats?

Yes. Delimiters can be switched between standard colons (00:1A:2B), hyphens (00-1A-2B), Cisco dotted quads (001a.2b3c), or unbroken strings.
