NetworkInterfaceComponent Enumeration
.NET Framework (current version)
Specifies the Internet Protocol versions that are supported by a network interface.
Assembly: System (in System.dll)
| Member name | Description | |
|---|---|---|
| IPv4 | Internet Protocol version 4. | |
| IPv6 | Internet Protocol version 6. |
The values in this enumeration are used by the Supports method to specify the Internet Protocol version supported by a network interface.
The following code example checks whether a network interface supports IPv4.
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
