Free MAC Address Generator
Generate random, cryptographically secure MAC addresses instantly — all locally, no server contact.
What does this tool do? Generate random MAC (Media Access Control) addresses for network testing, privacy protection, and penetration testing. Each address uses the locally administered address space with cryptographically secure randomness.

- Standard: IEEE 802 MAC-48 format — 6 octets, 48 bits total
- Locally Administered: Second-least-significant bit of first octet set to 1 (
0x02) to avoid conflicting with vendor-assigned addresses - Randomness: Uses
