Swisscom returns this IP address for blocked domain names most likely because it assumes this website is compromised (phishing, malware).

If you visit this IP address in a web browser you are redirected to https://www.swisscom.ch/abuse-info

That explains.  From a technical point of view, that is one of the most stupid things one can possibly do.  Whoever invented this, has no clue how the web works:

1) I point my browser to https://spectrum-conference.org (or any other domain where swisscom acts as the internet police)
2) Swisscom tampers with DNS and returns the address of one of their own servers
3) My browser opens a connection to it *and of course the website's HTTPS certificate does not match*
4) My browser shows an error message that a secure connection can not be made (at least all Apple device do this)
5) Swisscom malware page is not even displayed.


This website has a form to report false positive.
