Frequently Asked Questions
Can these MAC addresses be used in real networks?
Yes, but with caution. The generator creates valid addresses, but in production networks, it's recommended to use only locally administered addresses.
What is OUI and how does it work?
OUI (Organizationally Unique Identifier) is the first 3 bytes of a MAC address that identifies the manufacturer. We use real OUIs for authenticity.
What's the difference between unicast and multicast addresses?
Unicast addresses are used for individual devices, multicast for group addressing. The generator can create both types.
Is generation history saved?
Yes, the last 50 results are saved in your browser. You can also export addresses for storage.
How to verify MAC address uniqueness?
The generator creates pseudo-random addresses, but in networks you should additionally check uniqueness using 'arp' command or network scanners.
Is this suitable for virtual machines?
Absolutely! The generator is perfect for setting up virtual machines and containers. We recommend using locally administered addresses.
