(Go) Get Network Adapter IP and MAC Addresses

Retrieves network adapter information, including IP addresses (IPv4 and IPv6) and MAC addresses.

Note: This example requires Chilkat v10.1.3 or later.

    // Android:

    // On Android, accessing the MAC address directly is restricted on modern Android versions (API level 23 and above) due to privacy and security concerns. 
    // Apps targeting Android 6.0 (API level 23) or higher cannot access the MAC address of the device using standard APIs.
    // If you're developing for modern Android, consider using alternative identifiers (e.g., instance IDs) instead of the MAC address, as recommended by Google.
    // 
    // Chilkat will not return MAC addresses for Android, regardless of the API level.
    // Only IP addresses are returned for Android.
