Google Public DNS

Google Public DNS is a free global Domain Name System resolution service offered by Google, designed to make the Internet faster and more secure for users worldwide. Launched in 2009 as an experimental service, it has grown into one of the largest public DNS resolvers on the planet, processing billions of DNS queries per day. The service resolves domain names into IP addresses, acting as an intermediary between user devices and the authoritative DNS infrastructure that powers websites and online services. Google Public DNS supports modern security protocols including DNS-over-HTTPS and DNS-over-TLS, ensuring that DNS queries are encrypted and protected from interception, manipulation, or surveillance by third parties. The resolver employs advanced caching strategies and a globally distributed Anycast network to deliver low-latency responses, reducing the time it takes for web pages and applications to load. By operating its own DNS infrastructure with redundant capacity at locations worldwide, Google ensures high availability and resilience against DNS-based attacks including DDoS amplification attempts. The service is free to use and can be configured on any device or router by simply changing DNS settings to the designated primary and secondary resolver addresses, making enterprise-grade DNS resolution accessible to everyone.
