Google Public DNS is no longer considered as an experimental service.
This service offered by Google isn’t disappearing, but rather definitively moving from the experimental phase in which it was previously in. In trying to accelerate the web for all users, Google implemented their own DNS service in 2009.
Domain Name System makes an entry that corresponds to the domain name that users enter into a web browser and the IP address of the hosted service. Generally, the user allocates this task to DNS severs offered by their Internet provider.
With Google Public DNS, Google promises better performance thanks to prefetching to quickly respond to numerous requests, while protecting users from poison DNS cache attacks. There is also no redirection in the event that you mistakenly enter an address, and there is no filtering or blocking. As always, confidentiality questions are being asked. Google confirms that no information is cross referenced with their other services. Temporary logs with users IP addresses are deleted within 24 to 48 hours, while the logs kept for the long term (for security reasons and to improve service) are made anonymous.
According to Google, their DNS service has become the largest in the work, treating more than 70 billion requests per day. Close to 70% of the traffic comes from outside of the United States. Google Public DNS was such a success in experimental phase that it has now been made permanent.
The addresses of Google’s DNS servers are 220.127.116.11 and 18.104.22.168. In IPv6: 2001:4860:4860::8888 and 2001:4860:4860::8844.
