Answer 1

Here is a small console application example using Dns.GetHostAddresses... you might want to tweak it to your requirements..

using System;
using System.Net;
using System.Net.Sockets;
public class DnsListings
{
    public static void Main(String[] args)
    {
        Console.WriteLine(Socket.SupportsIPv6);
        String hostname = "";
        try
        {
            hostname = Dns.GetHostName();
            if (args.Length == 1)
                hostname = args[0];            
           Console.WriteLine("Getting Dns host entries for hostname " + hostname);
            IPAddress[] hosts = Dns.GetHostAddresses(hostname);
            foreach (IPAddress address in hosts)
            {
                Console.WriteLine("Address :{0}", address.ToString());
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }

    }

}

Answer 2

I'm using .NET 2.0.  I need to discover the link-local IPv6 address of the local machine programmatically, via managed code.

The only IPv6 address that Dns.GetHostAddresses returns is the loopback address, not the link-local one.  Note that I can see the IPv6 link local address when I run ipconfig.

Is there a way retrieve this address using managed code?

Thanks!

Thank for your reply, but I'm creating a Win Form app. It this app I have a Form (Form1), a Label (Label1) and a button (Button1). I would like to show in Label1 the Public IP when I click on button, do you know how can I do that?

Thanx.
