IPv4InterfaceProperties Class
Provides information about network interfaces that support Internet Protocol version 4 (IPv4).
Assembly: System (in System.dll)
| Name | Description | |
|---|---|---|
![]() | IPv4InterfaceProperties() | Initializes a new instance of the IPv4InterfaceProperties class. |
| Name | Description | |
|---|---|---|
![]() | Index | Gets the index of the network interface associated with the Internet Protocol version 4 (IPv4) address. |
![]() | IsAutomaticPrivateAddressingActive | Gets a Boolean value that indicates whether this interface has an automatic private IP addressing (APIPA) address. |
![]() | IsAutomaticPrivateAddressingEnabled | Gets a Boolean value that indicates whether this interface has automatic private IP addressing (APIPA) enabled. |
![]() | IsDhcpEnabled | Gets a Boolean value that indicates whether the interface is configured to use a Dynamic Host Configuration Protocol (DHCP) server to obtain an IP address. |
![]() | IsForwardingEnabled | Gets a Boolean value that indicates whether this interface can forward (route) packets. |
![]() | Mtu | Gets the maximum transmission unit (MTU) for this network interface. |
![]() | UsesWins | Gets a Boolean value that indicates whether an interface uses Windows Internet Name Service (WINS). |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
This class provides access to configuration and address information for network interfaces that support IPv4. You do not create instances of this class; they are returned by the GetIPv4Properties method.
For IPV6 properties, see GetIPv6Properties.
The following code example gets an GetIPv4Properties object and displays its data.
Public Shared Sub DisplayIPv4NetworkInterfaces() Dim nics As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces() Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties() Console.WriteLine("IPv4 interface information for {0}.{1}", properties.HostName, properties.DomainName) Dim adapter As NetworkInterface For Each adapter In nics ' Only display informatin for interfaces that support IPv4. If adapter.Supports(NetworkInterfaceComponent.IPv4) = False Then GoTo ContinueForEach1 End If 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 IPv4 interface properties. Dim p As IPv4InterfaceProperties = adapterProperties.GetIPv4Properties() If p Is Nothing Then Console.WriteLine("No IPv4 information is available for this interface.") GoTo ContinueForEach1 End If ' Display the IPv4 specific data. Console.WriteLine(" Index ............................. : {0}", p.Index) Console.WriteLine(" MTU ............................... : {0}", p.Mtu) Console.WriteLine(" APIPA active....................... : {0}", p.IsAutomaticPrivateAddressingActive) Console.WriteLine(" APIPA enabled...................... : {0}", p.IsAutomaticPrivateAddressingEnabled) Console.WriteLine(" Forwarding enabled................. : {0}", p.IsForwardingEnabled) Console.WriteLine(" Uses WINS ......................... : {0}", p.UsesWins) ContinueForEach1: Next adapter End Sub 'DisplayIPv4NetworkInterfaces
