Frequently Asked Questions

What is a MAC address?
A MAC (Media Access Control) address is a unique 48-bit identifier assigned to network interfaces. It is typically displayed as 6 pairs of hexadecimal digits (e.g., AA:BB:CC:DD:EE:FF).
Are generated MAC addresses valid?
Generated addresses follow the correct format but are random. They may conflict with real devices on a network.
Colon or hyphen separator?
Both are valid. Colons (AA:BB:CC:DD:EE:FF) are the Unix/IEEE standard. Hyphens (AA-BB-CC-DD-EE-FF) are used in Windows and Cisco equipment.
