Reliability and global reach. The most widely used public resolver in the world; almost guaranteed to be reachable from any network.
Official siteAbout Google Public DNS
Google Public DNS launched on December 3rd, 2009 as the first widely deployed public recursive resolver. It is operated by Google and serves trillions of queries per day from anycast nodes in over 100 locations worldwide, making it among the most reachable resolvers on the public internet.
The service performs no filtering and validates DNSSEC by default. Two log tiers exist: temporary logs (kept up to 24-48 hours) include the client IP for abuse and capacity analysis; "permanent" logs strip the IP before retention and preserve only coarse location (city level) and ISP. Google publishes its full privacy policy at dns.google/privacy.
The trade-off is the same as with Cloudflare: pointing your DNS at Google funnels another telemetry signal through a company that already has substantial visibility into your browsing. If that bothers you, Quad9 or Mullvad are worth considering. If you simply need a resolver that always works, 8.8.8.8 is the highest-baseline choice.
