❓ Frequently Asked Questions

General Questions

Q: Are the generated MAC addresses unique? A: Yes, within each generation batch, all MAC addresses are guaranteed to be unique. However, across different sessions, duplicates may occur due to the random nature.
Q: Can I use these MAC addresses in production? A: Generated MAC addresses are suitable for testing and development. For production use, ensure you use appropriate OUI prefixes that don't conflict with existing devices.
Q: What is an OUI prefix? A: OUI (Organizationally Unique Identifier) is the first 24 bits of a MAC address, assigned by IEEE to hardware manufacturers. It identifies the vendor of the network interface.

Technical Questions

Q: Does the tool support IPv6 interface identifiers? A: Currently, the tool focuses on MAC-48 addresses. IPv6 interface identifier generation may be added in future updates.
Q: Can I generate MAC addresses for specific vendors? A: Yes, by entering the vendor's OUI prefix in the custom prefix field, you can generate MAC addresses that appear to be from specific manufacturers.
