Google Public DNS is a free, global Domain Name System (DNS) resolution service.
You can use it as an alternative to your current DNS provider.
How can I take it out for a test run?
To try it out,
- configure your network settings to use the IP addresses 22.214.171.124 and 126.96.36.199 as your DNS servers or
- read the configuration instructions.
If you decide to try Google Public DNS, your client programs will perform all DNS lookups using Google Public DNS.
Why is DNS important?
The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often need multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
With Google Public DNS you can:
- Speed up your browsing experience.
- Improve your security.
- Get the results you want with no redirection.
