IPInterfaceProperties Class

Provides information about network interfaces that support Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6).

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

public abstract class IPInterfaceProperties
public abstract class IPInterfaceProperties
public abstract class IPInterfaceProperties
Not applicable.

This class provides access to configuration and address information for network interfaces that support IPv4 or IPv6. You do not create instances of this class; they are returned by the GetIPProperties method.

To access IPv4-specific properties, use the object returned by the GetIPv4Properties method. To access IPv6-specific properties, use the object returned by the GetIPv6Properties method.

The following code example displays address information.

public static void ShowIPAddresses(IPInterfaceProperties adapterProperties)
{
    IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
    if (dnsServers != null)
    {
        foreach (IPAddress dns in dnsServers)
        {
            Console.WriteLine("  DNS Servers ............................. : {0}", 
                dns.ToString()
           );
        }
    }
    IPAddressInformationCollection anyCast = adapterProperties.AnycastAddresses;
    if (anyCast != null)
    {
        foreach (IPAddressInformation any in anyCast)
        {
            Console.WriteLine("  Anycast Address .......................... : {0} {1} {2}", 
                any.Address,
                any.IsTransient ? "Transient" : "", 
                any.IsDnsEligible ? "DNS Eligible" : ""
            );
        }
        Console.WriteLine();
    }
        
    MulticastIPAddressInformationCollection multiCast = adapterProperties.MulticastAddresses;
    if (multiCast != null)
    {
        foreach (IPAddressInformation multi in multiCast)
        {
            Console.WriteLine("  Multicast Address ....................... : {0} {1} {2}", 
                multi.Address,
                multi.IsTransient ? "Transient" : "", 
                multi.IsDnsEligible ? "DNS Eligible" : ""
            );
        }
        Console.WriteLine();
    }
    UnicastIPAddressInformationCollection uniCast = adapterProperties.UnicastAddresses;
    if (uniCast != null)
    {
        string lifeTimeFormat = "dddd, MMMM dd, yyyy  hh:mm:ss tt";
        foreach (UnicastIPAddressInformation uni in uniCast)

            Console.WriteLine("     Duplicate Address Detection .......... : {0}", 
                uni.DuplicateAddressDetectionState);
                
            // Format the lifetimes as Sunday, February 16, 2003 11:33:44 PM
            // if en-us is the current culture.
            
            // Calculate the date and time at the end of the lifetimes.    
            when = DateTime.UtcNow + TimeSpan.FromSeconds(uni.AddressValidLifetime);
            when = when.ToLocalTime();    
            Console.WriteLine("     Valid Life Time ...................... : {0}", 
                when.ToString(lifeTimeFormat,System.Globalization.CultureInfo.CurrentCulture)
