  3. You can click "Reset" to clear the generated MAC address and start over.

Understanding MAC addresses

A MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment.

MAC address format

The MAC address is typically represented as 12 hexadecimal digits divided into 6 groups separated by colons (:) or hyphens (-). For example: 00:1A:2B:3C:4D:5E.

Types of MAC addresses

There are two main types of MAC addresses:

  • Organizationally Unique Identifier (OUI): The first 24 bits are assigned by the IEEE to organizations for their MAC address production.
  • Locally Administered Address: The last 24 bits can be assigned by the owner of the device and are used for random or locally administered addresses.

Applications

This calculator can be used for:

  • Testing network configurations
  • Creating virtual machines with unique network interfaces
  • Implementing network segmentation
  • Network troubleshooting
