Google public dns windows 10

Configure your network settings to use Google Public DNS

When you use Google Public DNS, you are changing your DNS «switchboard» operator
from your ISP to Google Public DNS.

In most cases, the Dynamic Host Configuration Protocol (DHCP) automatically
configures your system to use the IP addresses of your ISP’s domain name
servers. To use Google Public DNS, you need to explicitly change the DNS
settings in your operating system or device to use the Google Public DNS IP
addresses. The procedure for changing your DNS settings varies according to
operating system and version (Windows, Mac, Linux, or ChromeOS) or the device
(computer, phone, or router). We give general procedures here that might not
apply for your OS or device; consult your vendor documentation for authoritative
information.

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

Important: Before you start

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

We also recommend that you print this page, in the event that you encounter a
problem 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

Some devices require explicit values for all eight fields of IPv6 addresses and
cannot accept the abbreviated :: IPv6 address syntax. For such devices 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 hexadecimal digits are required.

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

You can configure Google Public DNS addresses for either IPv4 or IPv6
connections, or both. For IPv6-only networks with a NAT64 gateway using the
64:ff9b::/96 prefix, you can use Google Public DNS64 instead of Google
Public DNS IPv6 addresses, providing connectivity to IPv4-only services without
any other configuration.

Change your DNS servers settings

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

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

Windows

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

Example: Changing DNS server settings on Windows 10

1. Go to the Control Panel.
2. Click Network and Internet > Network and Sharing Center > Change
   adapter settings.

3. Select the connection for which you want to configure Google Public DNS. For
   example:

   • To change the settings for an Ethernet connection, right-click the
     Ethernet interface and select Properties.
   • To change the settings for a wireless connection, right-click the Wi-Fi
     interface and select Properties.

   If you are prompted for an administrator password or confirmation, type the
   password or provide confirmation.

4. Select the Networking tab. Under This connection uses the following
   items, select Internet Protocol Version 4 (TCP/IPv4) or Internet
   Protocol Version 6 (TCP/IPv6) and then click Properties.

5. Click Advanced and select the DNS tab. If there are any DNS server
   IP addresses listed there, write them down for future reference, and remove
   them from this window.

6. Click OK.

7. Select Use the following DNS server addresses. If there are any IP
   addresses listed in the Preferred DNS server or Alternate DNS
   server, write them down for future reference.

8. Replace those addresses with the IP addresses of the Google DNS servers:

   • 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 DNS64 instead of the IPv6
     addresses 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, enter

   addresses at the top of 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.
   • For IPv6-only: you can use Google Public DNS64 instead of the IPv6
     addresses in the previous point.
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 Network
Manager.

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. For
   example:
   • To change the settings for an Ethernet connection, select the Wired
     tab, then select your network interface in the list. It is usually
     called eth0.
   • To change the settings for a wireless connection, select the
     Wireless tab, then select the appropriate wireless network.
3. Click Edit, and in the window that appears, select the IPv4 Settings
   or IPv6 Settings tab.
4. If the selected method is Automatic (DHCP), open the dropdown and select
   Automatic (DHCP) addresses only instead. If the method is set to
   something 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 DNS64 instead of the IPv6
     addresses in the previous point.
6. Click Apply to save the change. If you are prompted for a password or
   confirmation, 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 are
specified in /etc/resolv.conf.

Example: Changing DNS server settings on a Debian server

1. Edit /etc/resolv.conf:

   sudo vi /etc/resolv.conf
   

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

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

   For IPv4:

   nameserver 8.8.8.8
   nameserver 8.8.4.4
   

   For IPv6:

   nameserver 2001:4860:4860::8888
   nameserver 2001:4860:4860::8844
   

   For IPv6-only, you can use Google Public DNS64 instead of the above
   IPv6 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 settings
in /etc/resolv.conf, you need to configure the DHCP client by editing the
client’s configuration file.

Example: Configuring DHCP client software on a Debian server

1. Back up /etc/resolv.conf:

   sudo cp /etc/resolv.conf /etc/resolv.conf.auto
   

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

   sudo vi /etc/dhcp*/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, write
   down the IP addresses for future reference.

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

   For IPv4:

   prepend domain-name-servers 8.8.8.8, 8.8.4.4;
   

   For IPv6:

   prepend domain-name-servers 2001:4860:4860::8888, 2001:4860:4860::8844;
   

   For IPv6-only, you can use Google Public DNS64 instead of the above
   IPv6 addresses.

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.

ChromeOS

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

Example: Changing DNS server settings on ChromeOS 71

1. Open the Settings menu.
2. In the Network section, select the connection for which you want to
   configure Google Public DNS. For example:
   • To change the settings for an Ethernet connection, click on the
     Ethernet section.
   • To change the settings for a wireless connection, click on the Wi-Fi
     section and select the appropriate network name.
   • Changing the DNS settings for a mobile data connection established with
     Instant Tethering isn’t possible. For mobile Wi-Fi hotspots that are
     manually set up, however, you can change the DNS settings using the
     instructions for a wireless connection.
3. Expand the Network section for the selected connection.
4. In the Name servers section:
   • For IPv4: Select the Google name servers button (or alternatively,
     select the Custom name servers button and enter 8.8.8.8 and
     8.8.4.4).
   • For IPv6: Select the Custom name servers button and enter
     2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64 instead of the IPv6
     addresses in the previous point.
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 server
settings; 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’s
   administration console. Most routers are manufactured to use a default
   address such as 192.168.0.1, 192.168.1.1, 192.168.2.1, or
   192.168.1.100. If none of these work, try to find the default gateway
   address in 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 and
   seconday 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 DNS64 instead of the IPv6
     addresses 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 require explicit values for all eight fields of IPv6 addresses and
cannot accept the abbreviated :: IPv6 address syntax. For such routers 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 hexadecimal digits are required.

iOS

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

1. Go to Settings > Wi-Fi.
2. Tap the ⓘ icon next to the Wi-Fi network that you want to change DNS
   servers for. Scroll down to find the DNS section and tap Configure DNS.
3. Tap Manual and add Google IP addresses. Optionally you can also remove
   all 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-Fi
network.

Android

Android 9 (Pie) or higher

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

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

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 TLS
connection 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 and
cannot configure private DNS for all networks. You can configure DNS for each
individual Wi-Fi network you use. This requires configuring all network
information manually and is only recommended for advanced users.

Mobile or other devices

DNS servers are typically specified under advanced Wi-Fi settings. However, as
every mobile device uses a different user interface for configuring DNS server
settings, 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 and
   secondary 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 DNS64 instead of the IPv6
     addresses 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 as
   http://www.google.com/). If it resolves
   correctly, quit the browser, load the page again and refresh it for several
   times to make sure the result is not from a cached web page.

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

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

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

   • If you are using Google Public DNS64 on an IPv6-only system, use
     http://[64:ff9b::d8da:e477]/ as the
     URL instead. If this test does not work, you do not have access to a
     NAT64 gateway at the reserved prefix 64:ff9b::/96 and cannot use
     Google Public DNS64.

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

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

3. Roll back the DNS changes you made and run the tests again. If the tests
   still 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.

purposes.

Switch back to your old DNS settings

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

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

Restart your system if necessary.

Quick Steps:

Step 1: Open the Control Panel from the Start menu
Step 2: Click Network and sharing Center
Step 3: Click Change adapter settings
Step 4: Right click on your active network adapter & choose properties
Step 5: Choose Internet Protocol Version 4 (TCP/IPv4) and click properties
Step 6: Enter the new DNS servers into the boxes under “Use the following DNS server addresses”

Background

By default, Windows will obtain the DNS servers from your internet connection. In most cases, these would be DNS servers from your ISP. Many ISP’s tend to cache DNS entries longer than they should and do not update records properly. Because of this, you may wish to use Google’s public DNS servers (or other DNS servers).

Каждый, наверняка, не раз уже слышал или читал о настройке DNS, которая помогает разрешать проблемы, связанные  с Интернет-подключением. В этой статье рассматривается ряд вопросов: что такое DNS-сервера, для чего используют адреса DNS, что такое публичные адреса Google, и как настраивать DNS-сервер в windows.

DNS —  протокол, который преобразовывает доменные имена веб-ресурса в IP-адрес. Каждый провайдер использует индивидуальный DNS-сервер, который работает по принципу, указанному выше. Однако, люди сталкиваются с случаями, когда на стороне провайдера возникают проблемы, неполадки, сбои и ошибки, из-за чего, при выполнении входа на ресурс, появляется сообщение, в котором будет значиться «DNS-адрес ****** не найден» или сообщение аналогичного характера. Если возникла подобная проблема, то не стоит опускать руки и ждать неизвестное количество времени, пока провайдер решит все-таки заняться проблемами, связанными с DNS-сервером. Гораздо проще воспользоваться публичными DNS-серверами.

Публичные сервера Google

Публичные сервера Google или Google Public DNS —  сервера DNS, которыми пользуются при возникновении проблем с доступом к интернет ресурсам, при этом использование DNS сервера Google не требует оплаты. Главный плюс использования DNS-серверов Google — работа без перебоев.

DNS 8.8.8.8. и DNS 8.8.4.4. — это те самые  знаменитые адреса DNS-сервера от компании Google.

Возникает вопрос: «Какой же сервер лучше использовать — провайдера или публичный?». Ответ: в теории разницы нет, но публичные сервера рекомендуется использовать в том случае, если на стороне провайдера возникли неполадки с DNS, либо если нет доступа к интернет ресурсу. Переход на публичный DNS — грамотное решение при возникших проблемах с сетевым подключением.

Как перейти на публичный DNS Google?

В настройках сетевого подключения у большинства пользователей указано автоматическое получение адреса DNS-сервера, но это легко изменить и выставить статический адрес DNS-сервера. В нашем случае это будут публичные DNS-сервера компании Google.

Чтобы выставить публичные адреса DNS-серверов для сетевого подключения в Windows, потребуется сделать следующие шаги:

1. Первым делом требуется открыть «Центр управления сетями и общим доступом». Это делается несколькими способами:

• Кликнув правой кнопкой мыши на значок «монитор» или «уровень сигнала» в области уведомлений, увидим меню с пунктом «Центр управления сетями…».
• Либо нажмите на клавиатуре Windows+R. Напишите в пустую строку «ncpa.cpl» без кавычек и нажмите Enter.

2. Далее ищем «Изменение параметров сетевого адаптера». Это в том случае, когда не видны значки сетевых подключений.

3. Дважды кликаем на иконку используемого подключения и переходим в свойства.

4. Выбираем протокол «Протокол Интернета версии 4 (TCP/IPv4)» и переходим в свойства протокола.

5. Поставьте галочку возле опции с наименованием «Использовать следующие адреса DNS-серверов», которая позволит ввести нужные адреса DNS-сервера.

6. В поле «Предпочитаемый DNS-сервер» прописываем 8.8.8.8 DNS сервер, а в «Альтернативный DNS-сервер»  – 8.8.4.4. Обратите внимание на точки-разделители между цифрами.

7. Подтверждаем изменения нажатием на «ОК».

Картинка с сайта: proxys.io

Если пользуетесь роутером, то следует иная комбинация настроек:

• В поле «Предпочитаемый DNS-сервер» прописываем DNS сервер роутера, который используется на устройстве, а в «Альтернативный DNS-сервер» – DNS-сервер Google (8.8.8.8).Адрес устройства указывается на нижней (или задней) части корпуса.

Картинка с сайта: proxys.io

Хочется упомянуть, что в статье рассматривались только DNS 8.8.8.8 и DNS 8.8.4.4 компании Google, но также возможно использование адреса и других публичных DNS-серверов, например, Securly или Comodo Secure DNS. Выбор не ограничен только Google.
