IPv4InterfaceProperties Class

Note: This class is new in the .NET Framework version 2.0.

Provides information about network interfaces that support Internet Protocol version 4 (IPv4).

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

public abstract class IPv4InterfaceProperties
public abstract class IPv4InterfaceProperties
public abstract class IPv4InterfaceProperties

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 static void DisplayIPv4NetworkInterfaces()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    Console.WriteLine("IPv4 interface information for {0}.{1}",
       properties.HostName, properties.DomainName);

    foreach (NetworkInterface adapter in nics)
    {
        // Only display informatin for interfaces that support IPv4.
        if (adapter.Supports(NetworkInterfaceComponent.IPv4) == false)
        {
            continue;
        }
        Console.WriteLine();
        Console.WriteLine(adapter.Description);
        // Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        // Try to get the IPv4 interface properties.
        IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();
        
        if (p == null)
        {
            Console.WriteLine("No IPv4 information is available for this interface.");
            continue;
        }
        // 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);
    }
}
