Huston, Geoff (11 de febrero de 2022). «Opinion: DNS4EU». APNIC. «Sony Music Germany bought a suit against the DNS open resolver provider Quad9 in a German court. The court ruled that Quad9 must block the resolution of a domain name of a website in Ukraine that itself does not hold copyright-infringing material, but instead contains pointers to another website that is reported to hold alleged copyright infringements. Quad9’s interpretation of this ruling is that queries received from IP addresses that can be geolocated to Germany must generate a SERVFAIL response from Quad9’s recursive resolvers.»

Consultado el 25 de junio de 2021. «Sony Music has won an injunction requiring a DNS resolver to block a popular piracy site. The ruling is the first of its kind and may signal a new direction in tackling music piracy. The order was issued by the District Court in Hamburg, Germany. The Hamburg Court ruling finds that DNS resolvers like Quad9 are not eligible for liability protections like ISPs and domain registrars. If Quad9 fails to block the infringing site, it faces a fine of up to $298,356.00 (€250,000) per infringing DNS query it processes and a potential prison stint of up to two years.»

Grüner, Sebastian (21 de junio de 2021). «Sony will DNS-Sperre bei Quad9 durchsetzen». Golem. Consultado el 21 de junio de 2021. «The DNS provider Quad9, which is now officially located in Switzerland, is held liable as a "Stoerer" (interferer) in this case, because the DNS resolution of the service enables copyright infringement. The "Stoererhaftung" (Breach of Duty of Care), its effects on copyright law, and any associated warnings against private individuals or even companies have been a point of contention in the law-making process of politics and the judiciary for decades. What is surprising about the current case is that Internet providers and registrars are actually exempt from "Stoererhaftung" (Breach of Duty of Care) under the so-called provider privilege. However, the Hamburg Regional Court apparently sees things differently.»

Quad9’s General Manager, John Todd, said: 'Quad9 derives its threat intelligence from qualified experts on malware and phishing, not from the claims of parties without relevant expertise. We would be unable to maintain our 98% success rate in blocking cyber-threats if we accepted input based on self-interested claims, rather than on forensics and expert analysis.' we could imagine that many more Rights Holders may rush to make use of this for similar websites. Naturally, Quad9 intends to appeal and so the battle is not yet over.»

There are other public DNS resolvers, but the link to them is not secure. This allows hijackings as well as third-party monitoring. The new Quad9 service on the other hand is operated by the not-for-profit Packet Clearing House (PCH), which manages large parts of the DNS infrastructure, and it allows access to the DNS over TLS. This makes it very difficult for third parties to listen in. And it makes it possible to authenticate the resolver.»
