IPInterfaceProperties.IsDynamicDnsEnabled Property

Definition

Namespace:

System.Net.NetworkInformation

Assembly:

System.Net.NetworkInformation.dll

Gets a Boolean value that indicates whether this interface is configured to automatically register its IP address information with the Domain Name System (DNS).

public:
 abstract property bool IsDynamicDnsEnabled { bool get(); };

[System.Runtime.Versioning.SupportedOSPlatform("windows")]
public abstract bool IsDynamicDnsEnabled { get; }

[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
member this.IsDynamicDnsEnabled : bool

Public MustOverride ReadOnly Property IsDynamicDnsEnabled As Boolean

Property Value

Boolean

true if this interface is configured to automatically register a mapping between its dynamic IP address and static domain names; otherwise, false.

Attributes

SupportedOSPlatformAttribute

Examples

The following code example displays the value of this property.

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

Dynamic DNS enables a client to inform the DNS servers that its dynamic IP address is mapped to its static host name.
