Hi Pondus,

Well then that IP should be kept an eye on, as it is dynamic dns which is often abused to spread malware all sorts.
Good this abuse has been taken down.
But ass -http://kuenstlerseele.net is up (on that same IP),  and whatever dynamic dns domain that gets hosted there,
we have to be cautious. 

Remember that the avast team members kept on alerting free afraid dot org, where at once your free sub-domains could not be your domain any longer.  A lot of dyndns domains are "above board", but the technology is also very attractive for cybercriminals.
