(VB.NET) 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.

Dim socket As New Chilkat.Socket
Dim json As New Chilkat.JsonObject

json.EmitCompact = False

' Note: The GetAdaptersAddresses method was added in Chilkat v10.1.3.
Dim success As Boolean = socket.GetAdaptersAddresses(json)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

' 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.
