About this tool
A MAC address identifies a network interface with six pairs of hexadecimal digits, usually written with colons between the pairs. This tool generates a fresh random address each time you press the button, in upper or lower case as you choose. The result is only a random string in the right format; it is not registered to any device or manufacturer, so use it for examples, tests and placeholders, not as the address of real hardware.
Frequently asked questions
Is the generated address tied to a real device?
No. It is a random string in MAC format only, with no link to any manufacturer or piece of hardware.
Can I generate the same address twice?
It is possible in theory, since the values are random, but with so many combinations it is very unlikely in practice.
