A MAC address is a 48-bit hardware identifier for network interfaces, usually shown as six pairs of hex digits. This tool generates random, locally-administered MAC addresses in the separator format you choose — one or many at a time, in your browser.
How to use it
- Choose the separator format (colon, hyphen or dot).
- Set how many to generate.
- Click Generate.
- Copy one or all.
About MAC Address Generator
Developers and network engineers need sample MAC addresses for testing device provisioning, DHCP reservations, network simulations and seed data. Typing them by hand is tedious and rarely produces well-formed values. This generator creates correctly formatted random MAC addresses with the locally-administered bit set, so they will not collide with real vendor-assigned hardware. It supports the common notations and generates everything locally.
FAQ
Are these safe to use for testing?
Yes. They use the locally-administered range, which is reserved for exactly this kind of non-hardware use.
What are the different formats?
The same address shown with different separators: colons (00:1A:2B...), hyphens (00-1A-2B...) or dots (001A.2B3C...).
What is a MAC address used for?
A MAC address is a hardware identifier assigned to a network interface. Random MAC addresses are useful for testing, privacy (MAC randomisation), and populating development or demo data without using real device identifiers.
