Standard FC2 OS with IPv6 6to4 setup as described on

I upgraded my problematic machine to FC3, which somehow broke 6to4, and I
didn't bother to reenable it again because the local DNS server (dnscache)
just drops AAAA queries on the floor anyway, leading to lots of timeouts
when trying to resolve host names, etc. Ever since 6to4 was turned off
on that box I stopped seeing these messages.
Surely it doesn't just drop AAAA queries on the floor, but sends an
error message?
If so, maybe then the problem is that glibc resolver cannot properly
handle such errors without undue timeouts.
Actually I've just sent a message on libc-alpha@ describing a similar
timeout issue:
http://sources.redhat.com/ml/libc-alpha/2005-01/msg00007.html
Maybe you could run a little bit of debug on whether the server sends
errors (which kind) and how the resolver reacts.
