互联网是发生大多数黑客攻击和隐私渗透^{(privacy infiltration)}的主要媒介。鉴于我们大部分时间都是闲置连接或积极浏览万维网，因此拥有安全可靠^{( safe and secure)}的互联网浏览体验对您来说非常重要。超文本传输​​协议安全^{(HyperText Transfer Protocol Secure)}（通常称为HTTPS ）的全球采用极大地帮助保护了 Internet 上的通信。DNS over HTTPS是^(HTTPS)谷歌^(Google)为进一步提高互联网安全而采用的另一项技术。但是，Chrome不会自动切换DNS 服务器^{(DNS server)}到DoH，即使您的互联网服务提供商^{(internet service provider)}支持它。因此，您需要学习如何在Chrome中手动启用基于 HTTPS^(HTTPS)的DNS 。

如何在 Google Chrome 中启用基于 HTTPS 的 DNS^{(How to Enable DNS over HTTPS in Google Chrome)}

DNS是域名系统^{(Domain Name System)}的缩写，用于获取您在网络浏览器^{(web browser)}上访问的域/网站的 IP 地址。但是，DNS服务器不加密数据^{(do not encrypt data)}，所有信息交换^{(information exchange)}都以纯文本形式^{(plain text)}进行。

新的 DNS over HTTPS 或DoH 技术^{(DoH technology)}使用现有的HTTPS协议来加密所有用户^{(encrypt all user)} 查询。^(queries.)因此，它提高了隐私和安全性^{(privacy and security)}。当您进入网站时，DoH会将^(DoH)HTTPS加密的查询信息直接发送到特定的DNS 服务器^{(DNS server)}，同时绕过ISP 级别的 DNS^{(ISP-level DNS)}设置。

Chrome 使用称为相同提供商 DNS-over-HTTPS 升级^{(same-provider DNS-over-HTTPS upgrade)}的方法。在这种方法中，它维护一个已知支持DNS-over-HTTPS的^{(DNS-over-HTTPS)}DNS提供商列表。它会尝试匹配您当前的DNS 服务提供商与提供商的^{(DNS service)}DoH 服务^{(DoH service)}（如果有）重叠。虽然，如果DoH 服务^{(DoH service)}不可用，默认情况下它将回退到DNS 服务^{(DNS service)}提供商。

要了解有关DNS的更多信息，请阅读我们关于什么是DNS及其工作原理的文章。

为什么在 Chrome 中使用 DNS over HTTPS？^{(Why use DNS over HTTPS in Chrome?)}

^(DNS)HTTPS上的^(HTTPS)DNS提供了几个好处，例如：

• 验证^(Verifies)与预期DNS 服务^{(DNS service)}提供商的通信是原始的还是虚假的。
• 加密^(Encrypts) DNS，有助于隐藏您的在线活动。
• 防止^(Prevents)您的 PC 遭受DNS欺骗和MITM攻击
• 保护^(Protects)您的敏感信息免受第三方观察者和黑客的攻击
• 集中^{(Centralizes)}您的 DNS 流量。
• 提高^(Improves)您的网络浏览器^{(web browser)}的速度和性能^{(speed & performance)}。

How to Enable DNS over HTTPS in Chrome

Τhe intеrnet is a primary medium νia which the majority of hacking attacks & рriνacy іnfiltration tаkes place. Given the fact that we are either idly connected or actively brоwsing through the world wide web most of the time, it is important for you to have a safe and secure internet browsing experience. The global adoption of HyperText Transfer Protocol Secure, which is commonly known as HTTPS has helped immensely in securing communication over the internet. DNS over HTTPS is another technology adopted by Google to further improve internet security. However, Chrome does not automatically switch DNS server to DoH, even if your internet service provider supports it. Thus, you need to learn how to enable DNS over HTTPS in Chrome manually.

How to Enable DNS over HTTPS in Google Chrome

DNS is an abbreviation for Domain Name System and fetches IP addresses of the domains/websites you visit on your web browser. However, DNS servers do not encrypt data and all information exchange takes place in plain text.

The new DNS over HTTPS or DoH technology uses the existing protocols of HTTPS to encrypt all user queries. It, thus, improves privacy and security. When you enter the website, DoH sends query information encrypted in HTTPS directly to the specific DNS server, while bypassing ISP-level DNS settings.

Chrome uses the approach known as same-provider DNS-over-HTTPS upgrade. In this approach, it maintains a list of DNS providers which are known to support DNS-over-HTTPS. It tries to match your current DNS service provider overlapped with the DoH service of the provider if there is one. Although, if there is unavailability of DoH service, it will fall back to the DNS service provider, by default.

To learn more about DNS, read our article on What is DNS and how does it work?.

Why use DNS over HTTPS in Chrome?

DNS over HTTPS offers several benefits, such as:

• Verifies whether the communication with the intended DNS service provider is original or fake.
• Encrypts DNS which helps to hide your activities online.
• Prevents your PC from DNS spoofing and MITM attacks
• Protects your sensitive information from third-party observers & hackers
• Centralizes your DNS traffic.
• Improves the speed & performance of your web browser.

Method 1: Enable DoH in Chrome

Google Chrome is one of the many web browsers that lets you take advantage of DoH protocols.

• Although DoH is disabled by default in Chrome version 80 and below, you can enable it manually.
• If you have updated to the latest version of Chrome, chances are, DNS over HTTPS is already enabled and protecting your PC from internet burglars.

Option 1: Update Chrome

Follow the steps given below to update Chrome in order to enable DoH:

1. Launch Google Chrome browser.

2. Type chrome://settings/help in URL bar as shown.

3. The browser will start Checking for updates as depicted below.

4A. If there are updates available then follow the onscreen instructions to update Chrome.

4B. If Chrome is in an updated stage, then you will get the message: Chrome is up to date.

Option 2: Use Secure DNS like Cloudfare

Although, if you do not wish to update to the latest version, due to memory storage or other reasons, you can enable it manually, as follows:

1. Open Google Chrome and click on the three vertical dots icon present at the top-right corner.

2. Choose Settings from the menu.

3. Navigate to Privacy and security in the left pane and click Security in the right, as shown highlighted.

4. Scroll down to the Advanced section and switch On toggle for the Use secure DNS option.

5A. Choose With your current service provider option.

Note: Secure DNS may not be available if your ISP doesn’t support it.

5B. Alternatively, select any one of the given options from With Customized drop-down menu:

• Cloudfare 1.1.1.1
• Open DNS
• Google (Public DNS)
• Clean Browsing (Family Filter)

5C. Moreover, you can choose to Enter custom provider in the desired field as well.

As an example, we have shown the steps for Browsing Experience Security Check for Cloudflare DoH 1.1.1.1.

6. Go to the Cloudflare DoH Checker website.

7. Here, you can view the results under Secure DNS.

Method 2: Switch DNS Server

Apart from enabling DNS over HTTPS Chrome, you will also need to switch DNS server of your PC to the one that supports DoH protocols. The best choices are:

• Public DNS by Google
• Cloudflare closely followed by
• OpenDNS,
• NextDNS,
• CleanBrowsing,
• DNS.SB, and
• Quad9.

1. Press the Windows key, type Control Panel and click on Open.

2. Set View by: > Large icons and click on the Network and Sharing Center from the list.

3. Next, click on the Change adapter settings hyperlink present in the left pane.

4. Right-click on your current network connection (e.g. Wi-Fi) and select Properties, as depicted.

5: Under This connection uses the following items: list, locate and click Internet Protocol Version 4 (TCP/IPv4).

6. Click the Properties button, as highlighted above.

7. Here, select Use the following DNS server addresses: option and enter the following:

Preferred DNS server: 8.8.8.8

Alternate DNS server: 8.8.4.4

8. Click on OK to save changes.

Due to DoH, your browser will be safeguarded against malicious attacks and hackers.

Pro Tip: Find Preferred & Alternate DNS Server

Enter your router IP address in the Preferred DNS server section. If you are not aware of your router IP address, you can find out using CMD.

1. Open Command Prompt from Windows search bar as shown.

2. Execute ipconfig command by typing it & pressing Enter key.

3. The number against the Default Gateway label is the IP address of the connected router.

4. In the Alternate DNS server section, type the IP address of the DoH-compatible DNS server you would like to use. Here’s a list of a few DoH-compatible DNS servers with their corresponding addresses:

DNS Server	Primary DNS
Public (Google)	8.8.8.8
Cloudflare	1.1.1.1
OpenDNS	208.67.222.222
Quad9	9.9.9.9
CleanBrowsing	185.228.168.9
DNS.SB	185.222.222.222

Frequently Asked Question (FAQs)
