Benefits of using Google DNS – and

  1. Ensures the DNS is being resolved correctly
    As you probably know, the default DNS on router is your ISP’s DNS. Often ISPs block access to certain resources be resolving their site names to a “wrong” IP-address. For instance if ISP wants to block access to their DNS would resolve to or another fake IP. To avoid such blocking it would be enough to set or on router or PC and use them to resolve the correct domain names.
  2. Faster resolve speed
    Google DNS resolves hostnames faster that many DNS servers that belong to ISPs.

How to Use Google DNS on Cellular Data

For the concluding part of our guide we left one more curious and rather difficult task to talk about – how to use Google DNS when your iPhone or Android is connected to the Internet via mobile data. The thing is that you cannot manually change DNS servers for your cellular data connection the way we showed this in the previous paragraph concerning Wi-Fi. Because there is simply no field to manually enter at least the primary IP address – 

The answer is use a third-party app. Unfortunately, there is no such app by Google (we hope that they will release one in the future), so you are to choose between several third-party apps on Google Play Store.

apps for using on mobile data

As a rule, they show you annoying ads until you pay money but nevertheless you can use them to actually switch your mobile data connection to Google DNS. Try some of them and choose the one you like.

Note that such apps work exactly as any VPN app. You can manually connect and disconnect VPN to start or stop using respectively, or make it connect automatically on startup or reboot.

Wrapping Up

We’d love to hear some feedback from you on the following questions:

  1. on what devices do you prefer to use Google Public DNS?
  2. what kind of connection do you use with (Wi-Fi or cellular data)?
  3. what are the reasons behind it (what purpose or what problems do you actually solve doing that)?

Thank you in advance and good luck!
