I just checked. Bear with me here:

In most imaged you will see for 

	printIt 	NetNameResolver useOldNetwork. "true"

If your VM and OS supports IPv6 (it should) you will see

	printIt		NetNameResolver hasIpv6PrimSupport. "true"

So you then can

	doIt		NetNameResolver enableIPv6: true.

If that worked, you will find

	printIt		NetNameResolver useOldNetwork. " false"

From now on, you will get more "interesting" network names. Look at the result of

	NetNameResolver localHostAddress.
	NetNameResolver localHostName.

(note that those are typically NOT localhost)
Also you should see

	printIt		NetNameResolver addressForName: 'localhost'. "::1(localhost),0(0)"


So far so good.

If you now try to, for example get some IPv6-enabled url, your should see

	printIt		(WebClient httpGet: 'http://ipv6-test.com') status. " 'HTTP/1.1 200 OK'"

But this won't probably work _unless_ you have the fixes in your image which I uploaded just 5 minutes ago (WebClient-topa.110, Network-topa.205) ;)

Best regards
