When you type
www.wikipedia.org in the address bar of your browser, you do not need anything but to get on Wikipedia. Most likely you are not very familiar with what is happening in the background with the
Domain Name System (DNS).
Today, as part of our ongoing efforts to
make the Internet faster , we are launching our DNS server, which we called
Google Public DNS and we invite you to try it.
Most of us are not familiar with DNS, because most often, everything is handled by our ISP (Internet Service Provider, ISP), but DNS provides important functions for the Internet. You can consider it a switchboard that converts easily remembered domain names - for example.
www.google.com - to a unique Internet Protocol (IP) number - for example, 74.125.45.100 - which computers use to communicate with each other.
Most Internet users perform hundreds of DNS queries every day, and some pages require multiple DNS queries even before the site loads. This can slow down your browsing experience. Our research has shown that speed
is important for users , so for the past few months, our engineers have been working to improve our public DNS server in order to make work on the Internet faster, safer and more reliable for users. You can read about the specific technical improvements that we have made to the documentation and get installation instructions on
our website .

If you are an experienced user and you can change network settings, go to
Google Code Blog for detailed instructions and more information on how to install Google Public DNS on your computer or router.
When people start using Google Public DNS, we plan to share with what we have learned with the web community and with other DNS providers in order to improve our browsing experience for users around the world. The goal of Google Public DNS is to help users all over the world, while at the same time helping tens of thousands of DNS providers improve their services to ultimately make the Internet faster for everyone.
