From Wikipedia, the free encyclopedia

Google Public DNS is a free DNS (Domain Name System) service announced on 3 December 2009[1], as part of Google's effort to make the web faster.[2][3]



The service is still experimental. It does not use third party DNS management software such as BIND, instead relying on a homegrown implementation, with limited IPv6 support, which conforms to the DNS standards set forth by the IETF.[4]

Privacy Issues

It is stated that for the purposes of performance and security, only the IP address (deleted after 24 hours), ISP and location information (kept permanently) are stored on the servers[5][6][7].


Google Public DNS provides the following recursive nameserver addresses for public use[8], mapped to the nearest operational server location by anycast routing[9]:



  • In December 2009, Google Public DNS was launched with its announcement[10] on the Official Google Blog by product manager Prem Ramaswami, with an additional post on the Google Code blog.[11]
