Hi,

newszilla6.xs4all.nl: connecting to port nntp...
warning: newszilla6.xs4all.nl: cannot resolve host name: Name exists in
DNS, but has no associated address ("A"-type DNS resource record).
newszilla6.xs4all.nl: connection failed.
Can you please send strace output? fetchnews is supposed to support
IPv6 - that error message is slightly misleading, it actually indicates
that the resolver didn't return any data.
Here's the relevant strace log:

And here's the relevant output of tcpdump when filtering for udp port

(192.168.23.3 is the DNS server, 192.168.23.6 is the server leafnode is
running one, and .home is my home network's domain)
