IMO the first step to take down a website from the internet should be the domain registrar and hosting provider, if you are a big company or just a normal guy that thinks this page violates xyz. It is very easy to find out the domain registrar and it may work to just a write a simple email, without the need for a lawsuite. And if they don't do what you think would be right, you *could* start a lawsuite with *them.*<p>Finding out the hosting provider *can* be easy, but sometimes it is impossible (cloudflare, etc). But even then looking up where the traffic goes is not that hard and writing them a simple email is also not that hard. Again, if they don't do what you think would be right, you *could* start a lawsuite with *them*.<p>Maybe they have done that and they both didn't comply, but why are they now fighting with a DNS resolver? This doesn't solve anything, anyone can still access that site, if they use another dns resolver or do the recursive resolving themselve.
