About the MAC Address Generator
A MAC address is a 48-bit hardware identifier, usually shown as six pairs of hexadecimal digits. They are useful as sample data for network testing and documentation.
This tool generates random MAC addresses with your preferred separator and case, entirely in your browser.
Because they are random, they are ideal for examples and tests rather than identifying real hardware.

Frequently asked questions
- Are these valid MAC addresses?
- They follow the correct 48-bit six-octet format, so they are structurally valid, but they are random and not tied to any real network card.
- What separator should I use?
- Colons (AA:BB:CC:DD:EE:FF) are most common on Linux and macOS; hyphens are common on Windows. Pick whichever matches your context.
- Can I generate several at once?
- Yes. Set how many you need and they are generated together.
