DNS Quad9 Public DNS 9.9.9.9 to block malware and phishing

eva2000 · Nov 21, 2017

A new free public DNS server by Quad9 has been announced using 9.9.9.9 DNS server IP https://arstechnica.com/information...ervice-blocks-malicious-domains-for-everyone/

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.

If a domain name is in the block list, the service simply responds to the query with an "NXDOMAIN" (non-existant domain) message. "It will break DNS queries," Rettinger said, "but it tends to work better than sinkholing"—the practice of forwarding bad domains to a host controlled by the service, as has been done with some seized botnet domains in the past—"because if you sinkhole, you can break other things."
