What is Google DNS
Google Public DNS represents two IP addresses for IPv4 – 126.96.36.199 and 188.8.131.52. 184.108.40.206 is the primary DNS, 220.127.116.11 is the secondary one. Google DNS service is free to use and can be used by anyone who has access to the Internet. You can use Google DNS IP instead of your ISP’s DNS servers to improve the resolve time and provide security.
- 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 example.com their DNS would resolve example.com to 127.0.0.1 or another fake IP. To avoid such blocking it would be enough to set 18.104.22.168 or 22.214.171.124 on router or PC and use them to resolve the correct domain names.
- Faster resolve speed
Google DNS resolves hostnames faster that many DNS servers that belong to ISPs.
Login to the web interface:
Go to Network → WAN Setup.
Check the flag Use these DNS Servers.
Type 126.96.36.199 into the Primary DNS field.
(We took Windows 10 to illustrate Google DNS Setup)
Right click on the network icon in the taskbar and click on Open Network and Sharing Center:
Click on your connection (or go to Change adapter settings and call for the connection properties):
Click on Properties:
Select Internet Protocol Version 4 (TCP/IPv4) in the list and click the Properties button:
Switch the lower selector to Use the following DNS server addresses.
Specify 188.8.131.52 as the Preferred DNS server.
Optionally specify 184.108.40.206 as the Alternate DNS server (or just leave the field blank).
Click OK to save settings:
Then press Close → Close in the previous Windows.
Note! It is much more easier to set up Google DNS on a router rather then an Android device. It makes sense to set up 220.127.116.11 on Android only if your do not have access to router admin page (for example if the router is not yours).
Go to Settings:
Press and hold on your network name (it doesn’t matter whether you are currently connecnted to it or not):
Tap on Modify network config:
Check the flag Show advanced options:
In IP settings select Static:
Specify Google DNS 18.104.22.168 and 22.214.171.124 as DNS1 and DNS2 respectively (you can fill only the DNS1 field and leave the second blank).
Tap on Save to apply changes to the network interface of your Android device:
You may also use Google DNS IPv6 address on your PC:
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 – 126.96.36.199.
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.
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 188.8.131.52 DNS server respectively, or make it connect automatically on startup or reboot.
We’d love to hear some feedback from you on the following questions:
- on what devices do you prefer to use Google Public DNS?
- what kind of connection do you use 184.108.40.206 with (Wi-Fi or cellular data)?
- what are the reasons behind it (what purpose or what problems do you actually solve using Google DNS)?
Thank you in advance and good luck!
