IPv6InterfaceProperties Class

Provides information about network interfaces that support Internet Protocol version 6 (IPv6).

Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

'Declaration
Public MustInherit Class IPv6InterfaceProperties
'Usage
Dim instance As IPv6InterfaceProperties

This class provides access to configuration and address information for network interfaces that support IPv6. You do not create instances of this class; they are returned by the GetIPv6Properties method.

For IPV4 properties, see GetIPv4Properties.

The following code example gets an IPInterfaceProperties object and displays its data.

Public Shared Sub DisplayIPv6NetworkInterfaces() 
    Dim nics As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Console.WriteLine("IPv6 interface information for {0}.{1}", properties.HostName, properties.DomainName)

    Dim count as Integer = 0

    Dim adapter As NetworkInterface
    For Each adapter In  nics
        ' Only display informatin for interfaces that support IPv6. 
        If adapter.Supports(NetworkInterfaceComponent.IPv6) = False Then
            GoTo ContinueForEach1
        End If
        count += 1

        Console.WriteLine()
        Console.WriteLine(adapter.Description)
        ' Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, "="c))

        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        ' Try to get the IPv6 interface properties. 
        Dim p As IPv6InterfaceProperties = adapterProperties.GetIPv6Properties()


        If p Is Nothing Then
            Console.WriteLine("No IPv6 information is available for this interface.")
            GoTo ContinueForEach1
        End If 
        ' Display the IPv6 specific data.
        Console.WriteLine("  Index ............................. : {0}", p.Index)
        Console.WriteLine("  MTU ............................... : {0}", p.Mtu)
    ContinueForEach1:
    Next adapter

    if count = 0 then
        Console.WriteLine("  No IPv6 interfaces were found.")
        Console.WriteLine()
    End if

End Sub 'DisplayIPv6NetworkInterfaces
void DisplayIPv6NetworkInterfaces()
{
    NetworkInterface* nics[] = NetworkInterface::GetAllNetworkInterfaces();
    IPGlobalProperties* properties = IPGlobalProperties::GetIPGlobalProperties();
    Console::WriteLine(S"IPv6 interface information for {0}.{1}",
        properties->HostName, properties->DomainName);

    System::Collections::IEnumerator* myEnum24 = nics->GetEnumerator();
    while (myEnum24->MoveNext())
    {
        NetworkInterface* adapter = __try_cast<NetworkInterface*>(myEnum24->Current);
        // Only display informatin for interfaces that support IPv6.
        if (adapter->Supports(NetworkInterfaceComponent::IPv6) == false)
        {
            continue;
        }
        Console::WriteLine();
        Console::WriteLine(adapter->Description);
        // Underline the description.
        Console::WriteLine(String::Empty->PadLeft(adapter->Description->Length,'='));

        IPInterfaceProperties* adapterProperties = adapter->GetIPInterfaceProperties();
        // Try to get the IPv6 interface properties.
        IPv6InterfaceProperties* p = adapterProperties->GetIPv6InterfaceProperties();

        if (p == 0)
        {
            Console::WriteLine(S"No IPv6 information is available for this interface.");
            continue;
        }
        // Display the IPv6 specific data.
        Console::WriteLine(S"  Index ............................. : {0}", __box(p->Index));
