I've got IPv6 set up and things work great if I also use IPv4. DNS lookups go over IPv4 according to what I have in /etc/resolv.conf and AAAA records are followed. However, if I decide to go with just IPv6 by simplifying my /etc/hostname.if file and using "inet6 autoconf" by itself, I cannot do any DNS lookups.
I'm thinking that somehow the rdns part of the router advertisement isn't working. If it were working correctly, would the provided IPv6 DNS server address show up in /etc/resolv.conf? I'm running -current but it's from about a month ago. Before I update it to try and fix a problem that I'm not sure is related to the snapshot I'm using, I figured I would check with misc@ and see if anyone's got a working configuration. If this is not supported yet, that'd be fine- I don't intend to forego IPv4 right now across the board.
