MAC Address Generator
Generate random MAC-style addresses with separator, case, and administration-bit options. Useful for testing, demos, and tooling.
This page generates MAC-style values for testing and tooling. It does not reserve or verify real hardware vendor assignments.

Privacy: generation runs locally in your browser. No values are stored or transmitted.
How it works
This page generates six random bytes and formats them as a MAC address. You can force the local-administration bit and clear the multicast bit in the first byte.
Examples
- 02:7F:9A:1C:44:E0 → locally administered unicast style
- AA-BB-CC-11-22-33 → hyphen-separated format
- 00163EABCDEF → no-separator format

- What is a locally administered MAC address?
It is a MAC address with the local administration bit set in the first octet. This is commonly used for virtual or software-defined addresses.
- Are generated values stored?
No. Generation runs locally in your browser and is not stored or transmitted.
