Other notes: * dig always resolves correctly, no router's address prepended.Could you share your dig command and output please.
Sure. Let's try www.sun.com, for example:
$ dig www.sun.com
; <<>> DiG 9.6.1-P3 <<>> www.sun.com
;; global options: +cmd
;; Got answer:

Now ping is wrong, as already mentioned:
$ ping -a www.sun.com
www.sun.com (2002:5f52:81a4:1::1) is alive
www.sun.com (137.254.16.57) is alive
* Linux and FreeBSD work fine with IPv6 on the same connection.Do they use the same nameserver in /etc/resolv.conf?
Yes.
Capture what's happening on the network as you make the requests using snoop or wireshark.
Tried that with ping -a www.sun.com * ping asked for www.sun.com AAAA and received an empty response. * ping asked for www.sun.com.podzimek.org (!!!) and received the address of my router (which explains a lot). * ping asked for www.sun.com A and received 137.254.16.57. * ping sent/received ICMPv6 and IPCMv4 packets. The conversation is attached as ping.pcap. I don't know how the 'www.sun.com.podzimek.org' domain is constructed. I don't have any 'search' line in /etc/resolv.conf, as already mentioned. My /etc/defaultdomain file contains 'helium.podzimek.org'. I don't know if this is related to host name resolution or not. The installer created that file and I have never touched it. Anyway it's the only file containing 'podzimek.org' in the whole /etc directory. :-) Andrej
