This is interesting. However, the first hurdle is something deeper than
DNS because simple connects using "telnet x.x.x.x 80" takes longer
with IPv6 enabled. Editing /etc/modprobe.conf did the trick for me.
strace show where/what calls are taking so long ?
And wether one doesn't get fooled by application bug(e.g. someone
calling gethostbyname with "192.168.0.2" or similar)
