Examples
The following code example displays the anycast addresses for the network interfaces on the local computer.
public static void DisplayAnycastAddresses()
{
int count = 0;
Console.WriteLine("Anycast Addresses");
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
IPAddressInformationCollection anyCast = adapterProperties.AnycastAddresses;
if (anyCast.Count >0)
{
Console.WriteLine(adapter.Description);
foreach (IPAddressInformation any in anyCast)
{
Console.WriteLine(" Anycast Address .......................... : {0} {1} {2}",
any.Address,
any.IsTransient ? "Transient" : "",
any.IsDnsEligible ? "DNS Eligible" : ""
);
count++;
}
Console.WriteLine();
}
}
if (count == 0)
{
Console.WriteLine(" No anycast addressses were found.");
Console.WriteLine();
}
}
Public Shared Sub DisplayAnycastAddresses()
Dim count as Integer = 0
Console.WriteLine("Anycast Addresses")
Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
Dim adapter As NetworkInterface
For Each adapter In adapters
Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
Dim anyCast As IPAddressInformationCollection = adapterProperties.AnycastAddresses

Console.WriteLine(adapter.Description)
Dim any As IPAddressInformation

Next any

Next adapter

Console.WriteLine(" No anycast addresses were found.")

Remarks
An anycast address identifies multiple computers. Packets sent to an anycast address are sent to one of the computers identified by the address. Anycast addressing is an IPv6 feature used to update router tables for a group of hosts.
