Yes you are wrong there. The correct nameservers for your setup should
be 194.109.6.66, 194.109.9.99 and 194.109.104.104.

The nameservers you are using now are the so-called authoritative
nameservers from xs4all. They only serve domains for which they are
the registered nameserver.

There are various reasons for splitting DNS services in authoritative and
caching servers. Though cache-pollution is no longer that big an issue there
are still good reasons for doing so.

Change your config to use the aforementiond nameservers (aka resolver.xs4all.nl)
and all will be well.
