Here are my results. For some reason the #addressesForName: is not 
seeing my wireless DHCP, though my machine claims it is ETHERNET.


(NetNameResolver addressesForName: NetNameResolver localHostName)
     select: [ :each | each addressFamilyName == #inet6 ]
     thenCollect: [ :each | each socketAddress hostNumber ].
  an OrderedCollection()

NetNameResolver addressesForName: NetNameResolver localHostName
  an OrderedCollection(127.0.1.1(callisto),0(0)-inet4-stream-tcp)

So far so good.

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

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


It's localhost is still ipv4 but supports ipv6 calls is what I am 
seeing, plus missing the wireless interface.

I appreciate your consideration,
Alan
