What's an anonymized MAC address?
A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications on the physical network segment. It is used to identify a device on a network and is typically written in hexadecimal notation. Each device on a network has a unique MAC address that is used to identify it and enable communication between devices.
An anonymized MAC address is a version of a MAC address that has been altered in such a way that it can no longer be used to identify the device or the individual associated with it
An anonymized MAC address typically has a random set of hexadecimal digits, which can be any combination of the numbers 0-9 and the letters A-F.
There are no specific rules for the values of an anonymized MAC address, as long as it is a valid MAC address format.
It's important to note that not all anonymized MAC addresses are valid, as some addresses are reserved for specific purposes and cannot be used. It's also important to check that the anonymized MAC address is not a globally unique (OUI) assigned by the IEEE, as these addresses are registered to specific manufacturers, and using them can be considered illegal.
The main reason to anonymize a MAC address is to protect the privacy of the user and to prevent tracking of the device by network administrators or malicious actors. Changing the MAC address can also be used to bypass network access controls or troubleshoot network issues.
