(JavaScript) 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.
var success = false;
var socket = new CkSocket();
var json = new CkJsonObject();
json.EmitCompact = false;
// Note: The GetAdaptersAddresses method was added in Chilkat v10.1.3.
success = socket.GetAdaptersAddresses(json);
if (success == false) {
console.log(socket.LastErrorText);
return;
}
console.log(json.Emit());

// Linux Sample Output:

// }
// -------------------------------------------------------
// 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.
