The first is Quad9, an industry consortium established by IBM, PCH and a long list of ICT security companies. Given the consortium's membership, it's no surprise that the service places particular emphasis on blocking referrals to domain names associated with abuse. Quad9 says that all query/response information will be retained â classified not by IP address but on the basis of geolocation â and shared with participants.
The second new DNS service is 126.96.36.199, an initiative by CDN provider Cloudflare and APNIC, the IP address administrator for the APAC region. The service is aimed explicitly at end users, with privacy protection as its central feature.
Manuals are available here [1, 2] for configuring a resolver running Unbound and configuring the 188.8.131.52 service on, respectively, Raspberry Pi and the OpenWrt platform. Those mini-systems are therefore now part of the same family as the Valibox, a device that lets end users immediately enable end-to-end DNSSEC validation on their wireless home/office networks.
Google's Public DNS and OpenDNS
The fourth major public DNS service is OpenDNS, a commercial service now under the Cisco umbrella, which doesn't support DNSSEC validation.
