Examples

The following code example displays the DNS suffix.

void DisplayDnsConfiguration()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum10 = adapters->GetEnumerator();
   while ( myEnum10->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum10->Current);
      IPInterfaceProperties ^ properties = adapter->GetIPProperties();
      Console::WriteLine( adapter->Description );
      Console::WriteLine( "  DNS suffix................................. :{0}", 
         properties->DnsSuffix );
      Console::WriteLine( "  DNS enabled ............................. : {0}", 
         properties->IsDnsEnabled );
      Console::WriteLine( "  Dynamically configured DNS .............. : {0}", 
         properties->IsDynamicDnsEnabled );
   }
}

public static void DisplayDnsConfiguration()
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine("  DNS suffix .............................. : {0}",
            properties.DnsSuffix);
        Console.WriteLine("  DNS enabled ............................. : {0}",
            properties.IsDnsEnabled);
        Console.WriteLine("  Dynamically configured DNS .............. : {0}",
            properties.IsDynamicDnsEnabled);
    }
    Console.WriteLine();
}

Public Shared Sub DisplayDnsConfiguration() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine("  DNS suffix................................. :{0}", properties.DnsSuffix)
        Console.WriteLine("  DNS enabled ............................. : {0}", properties.IsDnsEnabled)
        Console.WriteLine("  Dynamically configured DNS .............. : {0}", properties.IsDynamicDnsEnabled)
    Next adapter

End Sub

Remarks

The DNS suffix identifies the domain name (for example, "contoso.com") that is appended to an unqualified host name to obtain a fully qualified domain name (FQDN) suitable for a DNS name query. For example, if the local machine has "contoso.com" as its DnsSuffix, and must resolve the unqualified host name "www", the FQDN to query is "www.contoso.com".
