What is this?

This tool generates random MAC addresses. MAC addresses (media access control address) are assigned to computer hardware, specifically network interface controllers also known as ‘NIC’s, which are used as a unique identifier. They are most often encountered when configuring devices that interface via Bluetooth, Wifi or Ethernet. These MAC addresses are immutable meaning that they typically can not be changed and are assigned by the manufacturer at the time of manufacture. This address is found in both the read-only memory of the device and is often also printed on a label located on the device.

Because MAC addresses are used as unique identifiers which networking devices such as routers and switches use to identify target and source devices on a network, it is imperative that MAC addresses remain unique for each NIC on the network for the network to function correctly. MAC addresses are a 48-bit hexadecimal address which consists of six sets of two characters e.g. a4:00:31:9b:70:f3 and look similar to IPv6 addresses. An example use of this tool is below.

- Generate Sample MAC Addresses for App Development

This tool can help with randomly generating valid addresses which can then be used to fill data tables that need to sample data during development. It can be time consuming to manually generate these addresses by hand, use this tool to save time and work on other aspects of your project.

How to use this generator?

To use this random MAC address generator, simply choose how many MAC addresses you want to generate then choose the format of the results. By default the format is ‘Plain Text’ which presents the output in a single column of one MAC address per row. ‘JSON’ will process the results into JSON format which can be used for programming or database data entry purposes.
