I have the same problem like Stelian, but since I changed my provider
recently, I didn't suspect Rawhide. However, when following your steps,
I get this:
[root@localhost ~]# host www.union-invest.de
www.union-invest.de has address 193.24.35.212
;; connection timed out; no servers could be reached
;; connection timed out; no servers could be reached
The IPv4-address is returned without delay, but then it takes several
seconds for other requests to timeout. I won't post my tcpdump.dns.log
here, since it seems to be very similar to the one already posted by
Stelian.

Hah. John's suggestion was very valuable, because after removing my
IPv6-adresses ("ifconfig lo del ::1/128",...) I get
[root@localhost ~]# host www.union-invest.de
www.union-invest.de has address 193.24.35.212
[root@localhost ~]#
No timeouts and a very good response-time. :-) I had two IPv6-addresses
and two timeouts first and after removing both IPv6-adresses both
timeouts disappeard.
[root@localhost ~]# cat /etc/resolv.conf
