Google Public DNS

Google Public DNS is a free Domain Name System service offered by Google to the public, providing an alternative to ISPs and other DNS services like OpenDNS and Cloudflare. The service was announced on December 3, 2009, at the Google Ubiquity conference, with the goal of making the internet faster, more secure, and more reliable, as stated by Vint Cerf, a Google vice president. This initiative was also supported by ICANN, the Internet Corporation for Assigned Names and Numbers, and VeriSign, the registry operator for the .com and .net top-level domains. The service is built on Google's infrastructure, which includes data centers like the Council Bluffs facility and The Dalles facility, and is designed to be highly scalable and reliable, similar to other Google services like Google Search and Google Maps.

Introduction

The Google Public DNS service is designed to provide fast and secure DNS resolution, using anycast routing to direct users to the nearest DNS server, which can be located in data centers like the Google Chennai facility or the Google Singapore facility. This approach is similar to that used by other content delivery networks like Akamai and Limelight Networks. The service supports IPv6, as well as IPv4, and is compatible with a wide range of devices, including Android and iOS devices, as well as Windows and macOS computers, which can be configured to use the service using tools like NetworkManager or System Preferences. The service is also designed to be highly secure, using DNSSEC to validate the authenticity of DNS responses, which is an approach also used by other DNS services like OpenDNS and Cloudflare, and supported by organizations like the Internet Society and the Electronic Frontier Foundation.

History

The service was initially available at the IP addresses 8.8.8.8 and 8.8.4.4, which were chosen because they are easy to remember, similar to the IP addresses used by other DNS services like OpenDNS and Cloudflare. The service quickly gained popularity, with many users switching from their ISP's DNS service to the Google Public DNS service, which is also used by organizations like the Wikimedia Foundation and the Internet Archive.
