Hello,<br>
<br>
unfortunately there are not all names in the same domain.<br>
And I am not in control of the real name server. As far as I know the admin of the real server, it is likely that this server is missconfigured.<br>
<br>
A tcpdump of my machine doesn't show any outwards IPv6 traffic. There are a view AAAA-Records sent to the real server, which won't be answered.<br>
Finally there is sent a MX-Record, which apparently is answered.<br>
So I think, this is not an IPv6 problem.<br>
<br>
The answer of dnsmasq looks like this:<br>
<br>
host.subdomain.de has address 172.30.90.212<br>
;; connection timed out; no servers could be reached<br>
<br>

Are all the names in the same domain?
something like
local=/mydomain.com/
will stop all forwarding for *.mydomain.com. A and AAAA requests, but
not block A record answers that come from /etc/hosts.
I realise that this useless advise, if you don't have control, but the
real nameservers shouldn't be taking a long time to time out on AAAA
queries, so getting them fixed may be a solution.

No, but it's possible that you have missed the real problem: is the long
timeout a result of a client getting an IPv6 answer and then attempting
to make an IPv6 connection to a server? If that's the problem then
disabling IPv6 in the network configuration (or making it work) may be a
better solution.
