A Media Access Control (MAC) address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. On devices operating the Android operating system, this address serves the same function, identifying the device at the hardware level to facilitate network communication. Each Wi-Fi or Ethernet adapter within an Android device possesses its own unique MAC address.
This address is crucial for various network functions. It is employed for tasks such as network access control, where administrators can restrict access based on registered addresses. MAC addresses can also be used for tracking and identifying devices on a network. Understanding the purpose of this identifier is essential for troubleshooting connectivity issues, configuring network security settings, and managing devices connected to a network.
