IPv6 is not useless, and does not bring troubles. Don't spread FUD. IPv6
can be very useful.

First, remove the IPv6 interfaces from /etc/network/interfaces
(temporarily), check if the problem persists. If it does, the problem
has nothing to do with IPv6.

Another solution would be:

Check if the other interfaces are brought up (don't disable anything in
/etc/network/interfaces, but just run "ifconfig" for that), if they
aren't up, do an "ifup interfacename" to bring it up, see where it goes
wrong (ifup gives a bit more diagnostic info).

It /looks/ like you're connecting your sit1 tunnel to some place using a
hostname, but the DNS is not configured yet (or not yet available) when
the it is brought up.
