The MAC Address Generator can batch generate random MAC addresses with customizable prefix, quantity, letter case, and separator.

Core Features

• Batch generate 1-10000 random MAC addresses
• Optional MAC prefix (e.g., OUI vendor prefix)

• Local storage for settings persistence

How to Use

1. Set the quantity to generate
2. Optionally enter a MAC prefix
3. Choose letter case and separator

Notes

• Generated MAC addresses are random and do not correspond to real devices
• The first 3 bytes of a MAC address are the OUI (Organizationally Unique Identifier)
• When using a custom prefix, it must contain valid hexadecimal characters

Use Cases

• Network device testing and simulation
• Development and debugging
• Generate test data
