Random MAC Address Generator (Random MAC Generator)
Batch-generate random MAC addresses (6-byte / 48-bit). Each submit requests the server to regenerate and refresh the page.
Note: your prefix already sets the first byte, so Unicast/LAA options will not modify that byte.

Usage Instructions
- You can optionally enter a MAC prefix (for example OUI 00:1A:2B, or local prefix 02:00:00).
- Set separator and generation count, then click "Generate" (each click requests the server to regenerate and refresh the result).
- Click "Copy Results" to copy all results line by line to your clipboard.
- Generate unicast only (avoid multicast): when enabled, bit0 of the first MAC byte is forced to 0 to generate standard unicast addresses.
- Set as locally administered address (LAA): when enabled, bit1 of the first MAC byte is forced to 1, indicating a locally generated address.
- How to generate the MAC you need:
- VM / Docker / local testing -> Recommended: Unicast + LAA.
- Simulate a real vendor OUI -> Enter a 3-byte prefix (for example 00:1A:2B); keep unicast enabled, and choose LAA based on your needs.
- Completely random and safer local address -> Leave prefix empty; recommended: Unicast + LAA.
- Specify a full 6-byte prefix -> Generated MAC addresses will be identical.
- When the first byte is already fixed by prefix, Unicast/LAA options will not overwrite that byte.
