They don't as the use of tunnels has nothing to do with DNS. Tunnels
are simply the encapsulation of one protocol in another. The
encapsulation is done at the tunnel entrance and removed on exit.
Nothing outside of those two points knows or cares that there is a
I am assuming you are really talking about tunneling IPv6 packets in
IPv4 to get between IPv6 networks which lack direct connections But,
bu definition, a tunnel should be entirely transparent to things on
either side of the tunnel including DNS. Of course, that means that
the server on the other side of the tunnel must talk IPv6.
