> Hi, when we put our machines on the "ietf-v6ONLY" wife network, they do not get a DNS resolver as part of the RA packets and so they cannot resolve addresses and make connections.  Two of us have manually added "2001:df8:0:5::6" as the DNS server and have then been able to connect to sites.
> 
> We've seen this with Mac laptops running 10.8.x and also with an iPhone.   (I couldn't find anyone in the room with a non-Apple laptop to try it out.)
> 
> It would be great if we could get this fixed.
