We were only reporting IPv6 addresses when there were interfaces configured for
it (see getaddrinfo(3) and look for AI_ADDRCONFIG).

This has been changed to match MS behavior (mono-2-6 65be7a38 and master
d6a8c61a).

Note that in order to get IPv6 addresses, you will need to enable IPv6 in the 
config file of your application or in the global machine.config, like:
-----------
<configuration>
<system.net>
    <settings>
        <ipv6 enabled="true"/> 
    </settings>
</system.net>
</configuration>
------------








g at t61:/tmp$ cat dns.exe.config
<configuration>
<system.net>
    <settings>
        <ipv6 enabled="true"/> 
    </settings>
</system.net>
</configuration>

using System;
using System.Net;
class DNSTest {
    static void Main() {
        String Hostname = "www.kame.net";
        IPAddress[] IPs = Dns.GetHostAddresses(Hostname);
        Console.WriteLine("Found {0} IP addresses for {1}",
IPs.Length,Hostname);
        foreach (IPAddress i in IPs) {
            Console.WriteLine(i.ToString());
        }
    }
}
g at t61:/tmp$ cat dns.exe.config 
<configuration>
<system.net>
    <settings>
        <ipv6 enabled="true"/> 
    </settings>
</system.net>
</configuration>
g at t61:/tmp$ mono dns.exe 
Found 2 IP addresses for www.kame.net
203.178.141.194
