For most users, DNS lookups are handled automatically through an Internet service provider; they’re not tasks most of us see or devote much thought to. You do have the option, however, of using your own third-party DNS resolver. That’s where Google Public DNS comes in.
Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider.
To try it out:
- Configure your network settings to use the IP addresses 220.127.116.11 and 18.104.22.168 as your DNS servers or
- Read Google configuration instructions.
Google Public DNS and Your Privacy
What exactly will Google be watching with its new Google Public DNS service?
Here’s the breakdown of what is and isn’t collected:
• Your IP address: yes. But only temporarily. That data, Google says, is never stored for more than 24 to 48 hours, and it’s collected solely to identify technical problems and help protect from attacks.
• Your name or other personally identifying information: no. Google assures this type of data is never collected.
• Your location: yes. Google says it permanently stores “metro-level” info on your whereabouts for the purpose of debugging and improving the Google Public DNS experience. Most of this information is held for two weeks, Google says, though a “small subset” is sampled for permanent storage. The company promises that it never ties the location data to any other information collected from your session.
• The Web sites you look up: yes. But again, Google says that information is not stored along with any data that would identify who you are.
None of the information collected, Google says, is ever tied to your Google account, stored as part of your profile on any other Google service, or shared with any third-party provider.
