Configure your network settings to use Google Public DNS

Use OpenDNS Or Google DNS On Apple Mac OS X Go the Apple Menu “System Preferences” (or you can also use the Spotlight Search for this, just type the words “System Preferences” there). Now, search for “Network” and open it.

One of the best known is, of course, Google (8.8.8.8), which has, well, all the disadvantages of using a Google service. How to set up 1.1.1.1. It’s easy to set up the 1.1.1.1 DNS server. On a Mac, go to System Preferences, then Network. Click the padlock and enter an administrator’s user name and password. Click DNS, then click the Add button at the bottom of the DNS Servers list. Enter the IPv4 or IPv6 address for the DNS server. Below is a short list of commonly used public DNS servers. Secondary DNS servers can be added to add a layer of redundancy. Your Mac uses something called the Domain Name System (DNS) to access websites. It’s a system invisible to you, the user, and most people don’t even know it exists. But if the DNS servers you’re using are slow or unavailable, websites will load slowly or won’t load at all. Enter 8.8.8.8 and 8.8.4.4 to change the DNS Servers to Google on your Mac and click on OK to save these settings (See image above). Note: In case you want to use OpenDNS, enter 208.67.222.222 and 208.67.220.220 While you can enter as many DNS Servers as you want, macOS prioritizes connection to DNS servers based on the order in which they appear.

When you use Google Public DNS, you are changing your DNS 'switchboard' operatorfrom your ISP to Google Public DNS.

In most cases, the Dynamic Host Configuration Protocol (DHCP) automaticallyconfigures your system to use the IP addresses of your ISP's domain nameservers. To use Google Public DNS, you need to explicitly change the DNSsettings in your operating system or device to use the Google Public DNS IPaddresses. The procedure for changing your DNS settings varies according tooperating system and version (Windows, Mac, Linux, or Chrome OS) or the device(computer, phone, or router). We give general procedures here that might notapply for your OS or device; consult your vendor documentation for authoritativeinformation.

Depending on your system you may also have the option of enabling a newprivacy-oriented feature called DNS-over-TLS. This feature provides privacyand security for the DNS messages sent between your device and Google's DNSservers. Details on configuring this optional feature are in specific sectionsfor each system.

Important: Before you start

Before you change your DNS settings to use Google Public DNS, be sure to writedown the current server addresses or settings on a piece of paper. It is veryimportant that you keep these numbers for backup purposes, in case you need torevert to them at any time.

We also recommend that you print this page, in the event that you encounter aproblem and need to refer to these instructions.

Google Public DNS IP addresses

The Google Public DNS IP addresses (IPv4) are as follows:

• 8.8.8.8
• 8.8.4.4

The Google Public DNS IPv6 addresses are as follows:

• 2001:4860:4860::8888
• 2001:4860:4860::8844

You can use either address as your primary or secondary DNS server.

You can configure Google Public DNS addresses for either IPv4 or IPv6connections, or both. For IPv6-only networks with a NAT64 gateway using the64:ff9b::/96 prefix, you can use Google Public DNS64 instead of GooglePublic DNS IPv6 addresses, providing connectivity to IPv4-only services withoutany other configuration.

Change your DNS servers settings

Because the instructions differ between different versions/releases of eachoperating system, we only give one version as an example. If you need specificinstructions for your operating system/version, please consult your vendor'sdocumentation. You may also find answers on our user group page.

Many systems let you to specify multiple DNS servers, to be contacted inpriority order. In the following instructions, we provide steps to specify onlythe Google Public DNS servers as the primary and secondary servers, to ensurethat your setup correctly uses Google Public DNS in all cases.

Windows

DNS settings are specified in the TCP/IP Properties window for the selectednetwork connection.

Example: Changing DNS server settings on Windows 10

   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64instead of the IPv6addresses in the previous point.

9. Test that your setup is working correctly; see Test your new settings.

10. Repeat the procedure for additional network connections you want to change.

macOS

DNS settings are specified in the Network window.

Example: Changing DNS server settings on macOS 10.15

1. Click Apple menu > System Preferences > Network.
2. If the lock icon in the lower left-hand corner of the window is locked,click the icon to make changes, and when prompted to authenticate, enteryour password.

6. Click OK > Apply.
7. Test that your setup is working correctly; see Test your new settings.
8. Repeat the procedure for additional network connections you want to change.

Linux

In most modern Linux distributions, DNS settings are configured through NetworkManager.

Example: Changing DNS server settings on Ubuntu

1. Click System > Preferences > Network Connections.
2. Select the connection for which you want to configure Google Public DNS. Forexample:
   • To change the settings for an Ethernet connection, select the Wiredtab, then select your network interface in the list. It is usuallycalled eth0.
   • To change the settings for a wireless connection, select theWireless tab, then select the appropriate wireless network.
3. Click Edit, and in the window that appears, select the IPv4 Settingsor IPv6 Settings tab.
4. If the selected method is Automatic (DHCP), open the dropdown and selectAutomatic (DHCP) addresses only instead. If the method is set tosomething else, do not change it.
5. In the DNS servers field, enter the Google Public DNS IP addresses,separated by a comma:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64instead of the IPv6addresses in the previous point.
6. Click Apply to save the change. If you are prompted for a password orconfirmation, type the password or provide confirmation.
7. Test that your setup is working correctly; see Test your new settings.
8. Repeat the procedure for additional network connections you want to change.

If your distribution doesn't use Network Manager, your DNS settings arespecified in /etc/resolv.conf.

Example: Changing DNS server settings on a Debian server

1. Edit /etc/resolv.conf:

2. If any nameserver lines appear, write down the IP addresses for futurereference.

3. Replace the nameserver lines with, or add, the following lines:

   For IPv4:

   For IPv6:

   For IPv6-only, you can use Google Public DNS64instead of the aboveIPv6 addresses.

4. Save and exit.

5. Restart any Internet clients you are using.

6. Test that your setup is working correctly; see Test your new settings.

Additionally, if you are using DHCP client software that overwrites the settingsin /etc/resolv.conf, you need to configure the DHCP client by editing theclient's configuration file.

Example: Configuring DHCP client software on a Debian server

1. Back up /etc/resolv.conf:

2. Edit /etc/dhcp/dhclient.conf (or /etc/dhcp3/dhclient.conf):

3. If there is a line following request with only domain-name-servers,remove that line.

4. If there is a line containing domain-name-servers with IP addresses, writedown the IP addresses for future reference.

5. Replace that line with, or add, the following line:

   For IPv4:

   For IPv6:

   For IPv6-only, you can use Google Public DNS64instead of the aboveIPv6 addresses.

   Note: ISC DHCP v4.3.6 or higher is required for IPv6 domain-name-servers tobe processed; earlier versions would silently ignore such configuration.

6. Save and exit.

7. Restart any Internet clients you are using.

8. Test that your setup is working correctly; see Test your new settings.

Chrome OS

DNS settings are specified in the Network section of the Settings menufor the selected network connection.

Example: Changing DNS server settings on Chrome OS 71

1. Open the Settings menu.

5. Click outside the Network section to apply the settings.
6. Test that your setup is working correctly; see Test your new settings.
7. Repeat the procedure for additional network connections you want to change.

Routers

Every router uses a different user interface for configuring DNS serversettings; we provide only the generic procedure. For more information,please consult your router documentation.

To change your settings on a router:

1. In your browser, enter the IP address of your router to view the router'sadministration console. Most routers are manufactured to use a defaultaddress such as 192.168.0.1, 192.168.1.1, 192.168.2.1, or 192.168.1.100. Ifnone of them work or it’s changed, try to find the default gateway addressin the network settings panel of your system.
2. When prompted, enter the password to edit network settings.
3. Find the screen in which DNS server settings are specified.
4. If there are IP addresses specified in the fields for the primary andseconday DNS servers, write them down for future reference.
5. Replace those addresses with the Google IP addresses:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64instead of the IPv6addresses in the previous point.
6. Save and exit.
7. Restart your browser.
8. Test that your setup is working correctly; see Test your new settings.

Some routers use separate fields for all eight parts of IPv6 addresses andcannot accept the :: IPv6 abbreviation syntax. For such fields enter:

• 2001:4860:4860:0:0:0:0:8888
• 2001:4860:4860:0:0:0:0:8844

Expand the 0 entries to 0000 if four hex digits are required.

iOS

You can change DNS settings on iPhone, iPad, or iPod touch with the followingsteps.

1. Go to Settings > Wi-Fi.
2. Tap the ⓘ icon next to the Wi-Fi network that you want to change DNSservers for. Scroll down to find the DNS section and tap Configure DNS.
3. Tap Manual and add Google IP addresses. Optionally you can also removeall default DNS servers in the list.
   • For IPv4: 8.8.8.8 and/or 8.8.4.4
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844

Switching back to Automatic will restore the DNS server specified by the Wi-Finetwork.

Android

Android 9 (Pie) or higher

Android 9 supports 'Private DNS' which uses DNS-over-TLS to provide securityand privacy for your DNS queries. You can configure it with the following steps.

1. Go to Settings > Network & Internet > Advanced > PrivateDNS.
2. Select Private DNS provider hostname.
3. Enter dns.google as the hostname of the DNS provider.
4. Click Save.

Google Dns For Mac Windows 7

For more information see the Android blog post announcing the feature.Please note that in Android P, the default mode for Private DNS is 'Automatic'which means it uses the network specified DNS server and it attempts a TLSconnection to port 853 before falling back to UDP on port 53.

Older Android versions

Devices running versions older than Android 9 do not support DNS-over-TLS andcannot configure private DNS for all networks. You can configure DNS for eachindividual Wi-Fi network you use. This requires configuring all networkinformation manually and is only recommended for advanced users.

Mobile or other devices

DNS servers are typically specified under advanced Wi-Fi settings. However, asevery mobile device uses a different user interface for configuring DNS serversettings, we provide only the generic procedure. For more information,please consult your mobile provider's documentation.

To change your settings on a mobile device:

1. Go to the screen in which Wi-Fi settings are specified.
2. Find the screen in which DNS server settings are specified.
3. If there are IP addresses specified in the fields for the primary andsecondary DNS servers, write them down for future reference.
4. Replace those addresses with the Google IP addresses:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64instead of the IPv6addresses in the previous point.
5. Save and exit.
6. Test that your setup is working correctly; see Test your new settings.

Test your new settings

To test that the Google DNS resolver is working:

1. From your browser, enter a hostname URL (such ashttp://www.google.com/). If it resolvescorrectly, quit the browser, load the page again and refresh it for severaltimes to make sure the result is not from a cached web page.

   • If you are using Google Public DNS64 on an IPv6-only system, repeatthe above test with an IPv4-only hostname URL (such ashttp://ipv4.google.com/).

   If all of these tests work, everything is working correctly. If not, go tothe next step.

2. From your browser, type in a fixed IP address. You can usehttp://216.218.228.119/ (which points to thetest-ipv6.com website) as the URL.¹

   • If you are using Google Public DNS64 on an IPv6-only system, usehttp://[64:ff9b::d8da:e477]/ as theURL instead. If this test does not work, you do not have access to aNAT64 gateway at the reserved prefix 64:ff9b::/96 and cannot useGoogle Public DNS64.

   • If you are using an IPv6-only system without Google Public DNS64, usehttp://[2001:470:1:18::119]/ as theURL instead.

   If this works correctly, reload the page with a new opened browser to makesure the page is loaded from scratch. If these tests work (but step 1fails), then there is a problem with your DNS configuration; check the stepsabove to make sure you have configured everything correctly. If these testsdo not work, go to the next step.

3. Roll back the DNS changes you made and run the tests again. If the testsstill do not work, then there is a problem with your network settings;contact your ISP or network administrator for assistance.

If you encounter any problems after setting Google Public DNS as your resolver,please run the diagnostic procedure.

¹Google thanks Jason Fesler forgranting permission to use test-ipv6.com URLs for browser DNS testingpurposes.

Switch back to your old DNS settings

If you had not previously configured any customized DNS servers, to switch backto your old settings, in the window in which you specified the Google IPaddresses, select the option to enable obtaining DNS server addressesautomatically, and/or delete the Google IP addresses. This reverts your settingsto using your ISP's default servers.

If you need to manually specify any addresses, use the procedures above tospecify the old IP addresses.

Restart your system if necessary.

How to Clear DNS Cache on Your Mac And On Popular Browsers

When you want to visit a website, you usually enter the domain name into the browser's address, and your browser loads it, but web browsers use IP addresses to connect with websites. Thanks to the Domain Name System, or in short, DNS, you do not need to memorize complex IP addresses such as 1440:cb10:0088:1::b609:d7a2. It is a naming system that turns a domain name, for example, pcrisk.com, into an IP address (a unique label consisting of multiple characters).

In the early stages of the internet, it was way easier for users to use specific IP addresses as the network was very small. Due to the fast internet growth, as more people and devices started to join, it became quite hard to use IP addresses. Later, in 1983, Paul Mockapetris, a computer scientist, created the Domain Name System. It changed and improved throughout the years, but it is still used today to make our time on the internet more convenient.

As briefly mentioned before, DNS is responsible for translating a hostname into an IP address. It is like a contact book on your phone that connects the contact's name to their phone number and email. It is the same with website addresses as the DNS directory matches the names to IP addresses. There are four DNS servers involved in this process: recursive DNS server, root server, TLD nameserver, and authoritative nameserver.

The DNS recursor server is designed to receive inquiries from apps like web browsers. For example, your device makes a request to the recursive resolver, known as recursive DNS server, when it wants to find the IP address associated with the domain name you have entered in your browser. This server is usually operated by your ISP (Internet Service Provider) or another third-party provider. It also knows which other DNS servers it needs to contact to determine the web site's name with its IP address. So, for example, you want to visit pcrisk.com. The recursive resolver then sends a query to a root server, which has all information on top-level domains like .com, .net .uk, and so on. When the query reaches the correct root server, it goes to a TLD (Top Level Domain) server, which has the second-level domain information, meaning it stores the website name that goes before top-level domains. For example, that piece of information for pcrisk.com is 'pcrisk'. When this information is acquired, the request then goes on to the final server that holds the necessary information about the sites and their IP address - an authoritative DNS server. Then, all the information about the site is sent back to the 'client', and you are then able to access the website. Even though this process can look complicated, it only takes a few milliseconds.

When you enter a web address into your browser's address bar, the Domain Name System translates the domain name into an IP address, and your browser, by default, caches and stores information of the site for a set amount of time. It is done so that the DNS query can be resolved faster as the need for requesting additional queries to other servers is eliminated as the browser's cache is the first step to check for requested DNS records. That is why when you go to the same website for a second time, you might notice it loading much quicker than the first time you visited. DNS caching can also reduce CPU (Central Processing Unit) consumption.

Unfortunately, with your browser's storing DNS cache, you might sometimes not be able to access some websites that you already visited. This is because a website might migrate to a new domain, which means its DNS address changes. Supposedly you are trying to access a website from a recently visited section, and you can not reach it, even though you know it is up and running. In this case, when you try to access it, the DNS records go to your browser's stored DNS cache and rely on the outdated information. That is why flushing the DNS cache can help with such issues. It can also clear all infester DNS cache records, which help keep you safer on the web.

To find out how you can flush your DNS cache on your Mac and in popular bowsers, read down below.
