New “Quad9” DNS service blocks malicious domains for everyone | Ars Technica

The Global Cyber Alliance (GCA)—an organization founded by law enforcement and research organizations to help reduce cyber-crime—has partnered with IBM and Packet Clearing House to launch a free public Domain Name Service system. That system is intended to block domains associated with botnets, phishing attacks, and other malicious Internet hosts—primarily targeted at organizations that don’t run their own DNS blacklisting and whitelisting services. Called Quad9 (after the 9.9.9.9 Internet Protocol address the service has obtained), the service works like any other public DNS server (such as Google’s), except that it won’t return name resolutions for sites that are identified via threat feeds the service aggregates daily.

“Anyone anywhere can use it,” said Phil Rettinger, GCA’s president and chief operating officer, in an interview with Ars. The service, he says, will be “privacy sensitive,” with no logging of the addresses making DNS requests—”we will keep only [rough] geolocation data,” he said, for the purposes of tracking the spread of requests associated with particular malicious domains. “We’re anonymizing the data, sacrificing on the side of privacy.”
