What is DNS and how does it work?

DNS stands for Domain Name System. It is a system
that allows you to assign readable names to the IP addresses of devices connected to the Internet. In this way, users can access websites, online services, or network resources using easy-to-remember names, such as www.bing.com, rather than long and complex numbers, such as 204.79.197.200.

The way DNS works is based on a hierarchy of servers distributed around the world. They store and update information about names and associated IP addresses. When a user enters a domain name in his browser, the DNS system looks up the server that contains the information about that domain and returns the IP address. Thus, the browser can then establish a connection to the server hosting the requested website and display its content to the user.

How to use AdGuard’s DNS service on your Android phone

The AdGuard DNS is an alternative service to the one offered by our Internet provider or our router. In addition to performing the basic function of resolving domain names, it also filters the requests that are made to advertising and tracking servers. Preventing them from being loaded on our device. Thus, we can surf the Internet without seeing ads or being tracked by third parties.

Follow the steps below to use the AdGuard DNS service:

First step

Go to the Settings application on your Android phone.

Second step

Then go to Network & Internet>Advanced>Private DNS. You can get to this option easier and faster by typing “Private DNS” in the search box of the Settings app.

Third step

After that, once you have selected Private DNS, tap on “Private DNS provider hostname”.

Fourth step

Now, you have to enter the AdGuard DNS address:

dns.adguard.com (to block advertising and tracking).

Fifth step

Finally, click on Save and that’s it!

With these steps, you will have already activated AdGuard DNS on your Android device. And you can enjoy cleaner and safer browsing. Of course, keep in mind that this method only works if you have Android 9 or higher, and that it may not be compatible with some public or private WiFi networks that require specific configuration.

Alternatively, you can activate this DNS from a more intuitive interface with the AdGuard app that you can download from Google Play.

Google Play | AdGuard for Android

Is it safe to use the AdGuard DNS service?

The dns.adguard.com is a public DNS service that protects against tracking, phishing, and malware. According to its website, dns.adguard.com uses encryption and does not keep any logs of user queries. However, as with any DNS service, there is a risk of bugs, unwanted failures, delays, or crashes. It is therefore recommended to
use dns.adguard.com with caution and verify its reliability and performance before relying on it for browsing. Thank you for reading us. Goodbye!

How Smart DNS works

DNS is used to link a domain name to an IP address. That is, if you enter osradar.com in your browser, your system automatically translates that information and returns the IP that corresponds to that page. You don’t need to remember meaningless numbers, but simply the domain name. Logically, when we send that DNS request, we are sending information. They are going to know certain information about our equipment. That’s where Smart DNS comes in. In effect, what it does is hide the DNS address of our device when we redirect queries through a remote server.

Normally, you will use the DNS of the Internet operator you have. It will come automatically configured this way, for example on Windows. But you can also use the DNS of services such as Google, Cloudflare or Quad9, among many others. However, when using Smart DNS, you are going to enter the Internet with their DNS. In effect, it hides your real ones, the ones you have configured on your computer. It will change the DNS you have configured locally to theirs remotely.

More privacy does not necessarily mean more security

However, you should know that it will not hide data such as your IP, for example. It is not something that protects your security. It allows you to access content that is geographically restricted. In fact, this is what has led to a considerable increase in the use of this type of service. This is not a novelty, as it has been around for 10 years, but it is in recent times that we have seen great growth.

Think of a movie or series you want to watch from Netflix, but it is not available in the USA or in the country you are in. What Smart DNS does is to hide your DNS, to mask them, so you can access content that may be geographically blocked. In part, it will act as a VPN, but it is not the same.

Differences with a VPN

We can say that there are major differences between a VPN and Smart DNS. You should not confuse what each service does, as you could have security and privacy problems. A VPN will hide the IP address and encrypt the data. This is very useful if you browse over a public Wi-Fi network, as it will protect your security.

However, Smart DNS does not do that. It does not hide the IP, nor does it encrypt the connection. In fact, they are not going to improve your security. Now, don’t VPNs also serve to avoid geo-blocking? Yes, it is true that they also have this function. However, there are differences that make many users opt for Smart DNS.

A clear difference between VPN and Smart DNS is speed. It is a fact that when browsing via VPN, the connection will be slower. You may even experience outages or have problems accessing certain services if you use a program that is not very reliable, such as the free ones.

Smart DNS does not encrypt the connection data. This has no impact on the connection speed. You will have no problems, for example, downloading from the cloud at good speed, streaming in high definition. Or play online and see that the game is constantly cut off.

On the other hand, you should bear in mind that some VPN services also offer Smart DNS. In other words, they will also change your computer’s DNS while encrypting the IP address and browsing data for greater security.

Advantages of using Smart DNS

Having seen how Smart DNS works and how it differs from a VPN, let’s take a look at the most important advantages of navigating through this type of service.

• The main advantage is that you will be able to enter websites that are blocked. This is very useful if you want to enter certain platforms that may be restricted in your country. For example, some movies or series on services like Netflix. As well as enter social networks or use certain applications that are banned in other countries.
• Another crucial point is that it will not slow down the connection. Unlike what happens with a proxy or VPN, in this case you will not notice a drastic drop in Internet speed, both upload and download. You will be able to browse without those annoying limitations.
• In addition, they are usually elementary to use and can be configured on multiple platforms. This allows you to browse through Smart DNS on your computer, cell phone, etc. You will have a wide range of options in this regard.

There are both free and paid Smart DNS services. However, as in the case of VPNs, if you want an option that really works well, you will usually have to opt for a paid one. You will find services that offer Smart DNS, such as NordVPN, SmartDNSProxy, Unlocator or Ironsocket. Each of these options has its peculiarities, but basically the end goal is the same.

Conclusion

In short, we can say that Smart DNS is a very intriguing alternative to the use of VPN or proxy. Especially when you only want to access restricted content. For example, watching a Netflix video that is not available in one place or using any blocked application. In addition, it is important when you need the Internet speed to be adequate and to avoid outages.

However, you should bear in mind that they will not encrypt the connection, nor hide the IP address, as a VPN service does. This must be considered, since in this case, the security when surfing the net will not be the same. If, for example, you are going to connect to a public network, your data could be at risk. Goodbye!

How to bypass the firewall

A firewall is a software and/or hardware system that is responsible for controlling all incoming and outgoing connections between the local network and the Internet. It is also responsible for logically separating different subnets that we have in different VLANs. Its main function is to prevent and protect our private network from possible intrusions. With this in mind, it blocks access from the outside to the inside. A firewall can also be configured to limit traffic from the internal network to the external network. Therefore, we might encounter some kind of blocking implemented by the network administrator.

In many occasions users want to access the Internet without any kind of limitation. Indeed, knowledge of how to access blocked websites in a school or university can be an asset among students. The same is true at work. It is possible to want to access a resource blocked by the firewall. Consequently, it may be necessary to attempt to bypass the organization’s firewall.

Here we are going to analyze how to bypass the school, university or work firewall. Accordingly, we will check methods to bypass the firewall. This depends on how that particular firewall works. Some work at the DNS level. That is to say, the firewall itself will be in charge of providing us with local DNS servers where the filtering is done, in addition, the possibility of using external DNS such as those of Google or Cloudflare is blocked. Another common method of blocking is to check the SNI field of HTTPS connections. As a result, we could allow or block access to certain web pages. Finally, they could do a deep traffic inspection (DPI) to block traffic that they have defined in the rules.

Use a proxy server

Proxies are services that will act as intermediaries and handle requests for us. For example, if you want to view a game website, it is quite likely that you will look it up by typing the URL in the address bar and the firewall will block it. A proxy server avoids this because you are not visiting the game website directly. What we do is go to the proxy page, and you tell it to go to that page instead of us. It then shows you all the requested content, while the firewall only sees the proxy URL.

There are several types of Proxy, those based on HTTP and HTTPS. It is the latter that you should use. Indeed, if you use HTTP, all traffic will be unencrypted and could easily be blocked by the firewall. When using an HTTPS proxy, all communications between the user’s computer and the proxy server will be fully encrypted. Consequently, it is ideal for maintaining privacy and keeping the firewall out of the way.

When using a web proxy, you must consider that the browser you use must be correctly configured. Therefore, you must go to the network section and configure the IP address and port of the proxy, as well as the protocol it is using. Once configured, we will be able to surf the Internet through the Proxy. However, the traffic used by other programs such as Skype or Slack will go through the main Internet connection. In reality, there is no complete forwarding of traffic as with VPN services, only web traffic will move through the Proxy.

Use a VPN to keep your traffic out of sight

A VPN is even more complete than a proxy and also makes it possible to bypass the firewall at work or school. In this case, it is as if our data travels hidden through a tunnel thanks to encryption. Consequently, it keeps us safe from prying eyes such as the school itself, the Internet provider and more. In this way of working, our computer sends this encrypted data to a VPN server, which decrypts our data. It then reads where we want to go and goes there. It then sends the traffic back encrypted and bypasses the firewall without any problems.

A significant detail of VPNs is that all network traffic will go from your PC to the VPN server. In fact, it will not only be the web traffic, but also the Internet traffic of any program or process we are using.

Google Translate

Another method is to use Google Translate. Here we have to use the translation page function to use it. Then, when Google Translate translates that page, it loads the page on the server, translates it and sends us the result. This little trick is widely used to bypass firewalls when a website is blocked. In effect, we will use Google’s services to take us to the final website. However, this method has its limitations. Besides, it is quite annoying to have to use the hyperlinks inside the Google translator.

The use of this trick is basic. Just go to the Google Translate page. Once there, please upload the URL of the blocked web page. Allow the algorithm to detect the language automatically. Then, you have to translate the website to a different language than the original one. That’s it! As a result, you will have access to the website but in a different language than the original one. However, it is a way to access. Beyond the language limitation, it is likely that your organization will also block this domain from Google because it has been known to do this kind of thing. As a result, it may not work.

Type the IP address of the website

When surfing the Internet we use domain names because they are easier to remember. The reality is that those names are in charge of translating them to the DNS servers and then sending us to that IP address. If we put that public IP in the address bar of the browser we can bypass the firewall. Of course, as long as the firewall does not have a blacklist of IP addresses that cannot be accessed or does traffic inspection. A web page that we can use to find out that IP is WhatIsMyIPAddress.

This form of connection will only work in cases where the firewall blocks traffic at the DNS level. However, if the blocking is through DNS and IP, it will not work because it will also detect that we are connecting to unauthorized websites. If you cannot use Proxy and VPN to attempt to bypass firewalls, this trick might work well for you to connect without limitations. However, you will have to know in advance all the IP addresses of the websites you want to access, so it will be quite cumbersome.

Uses DNS over HTTPS

The DOH protocol allows DNS requests and responses to be made through the HTTPS protocol in a fully encrypted manner. If your firewall is blocking access to the Internet through DNS, if you use DOH in the web browser, you will be able to bypass the firewall easily and simply. This is because blocking this protocol is really complicated. Indeed, you would have to block HTTPS accesses to all DNS servers that support this protocol, including Google, so as a general rule this is not blocked.

This DOH protocol is already found in major web browsers such as Chrome or Firefox. It is even present in Microsoft systems. Consequently, it would be advisable to check your DNS settings over HTTPS if you can because this way you could bypass the DNS blocking. Okay, so we have seen how to bypass a firewall. We hope you will use this guide to avoid limitations in your work or school. See you soon.

Why do we need IPv6 DNS?

We are currently living in an era of transition from IPv4 to IPv6 protocol. This is because conventional IP addresses are now completely exhausted. As we have connected more and more devices to the Internet, we have run out of public IP addresses. This is vital for the different Internet services and ourselves to be able to access the Internet.

Over time, technologies have been developed to attempt to mitigate the accelerated depletion of public IPv4 addresses. One example is use NAT to exit to the Internet from several clients through the same public IP, using the different TCP and UDP ports. More aggressive techniques such as CG-NAT have also been used. There our public IP address is shared with other clients of the same operator, and where we cannot do the typical port forwarding. Therefore, we will not be able to host at home any kind of FTP server, VPN or any other service that requires port forwarding, such as online games.

IPv4 and IPv6 addresses are incompatible with each other. However, there are currently several methods of transition. On the other hand, if your operator provides you with a public IPv6 address, you will have to use DNS servers with IPv6 addresses. Logically, this is the only way to resolve domains that are also IPv6. Otherwise, you will not be able to surf the Internet correctly.

Next, we are going to recommend a list of DNS servers that work directly in IPv6. This way, you will be able to surf the Internet with IPv6 addressing correctly and without problems.

IPv6 DNS Servers

Currently, we have several providers of DNS servers with IPv6 protocol. Certainly, our operator should provide us with DNS with this network protocol. However, you may be interested in using the popular Google DNS, Cloudflare DNS or OpenDNS among many others. Below is a complete list of the main DNS servers for fast browsing.

Google

Google DNS are the most used worldwide for their speed in resolving domains. In addition, they are the ones that offer the best results to most users. An essential detail is that Google has data centers all over the world. They also use anycast IP addresses to reach those geographically closest to them, even though we always use the same IP addresses for everyone. Google’s DNS servers with IPv6 are as follows:

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

As you can see, the termination of these DNS is a wink to the popular 8.8.8.8.8 and 8.8.4.4.4 that are available for IPv4 addressing. Finally, you should know that these Google DNS support both DNS over HTTPS and DNS over TLS.

Cloudflare

Cloudflare’s DNS are widely used worldwide. Cloudfare is a large Internet company that provides CDN services worldwide. It also offers services to mitigate DoS and DDoS attacks quickly and efficiently. If you have been using your carrier’s or Google’s DNS all your life, we recommend giving Cloudflare’s DNS servers a try. It also has WARP, which is the company’s free VPN service, with the aim of protecting our Internet connection. Cloudflare’s DNS servers with IPv6 are as follows:

• 2606:4700:4700::1111
• 2606:4700:4700::1001

If you want to use built-in malware filtering, you will need to use the following:

• 2606:4700:4700::1112
• 2606:4700:4700::1002

If you want to use malware filtering and block adult content, you will need to use the following:

• 2606:4700:4700::1113
• 2606:4700:4700::1003

Of course, these DNS servers also support both DNS over HTTPS and DNS over TLS. This way they provide encryption and authenticity to the servers, and prevent many DNS related attacks.

OpenDNS

OpenDNS is one of the world’s best-known DNS service providers. Before Google launched its DNS servers, OpenDNS servers were widely used for their speed and reliability. In addition, they can provide parental control filtering. Another critical feature of OpenDNS is the privacy it provides to its users. Indeed, they promise or collect information about the queries of different customers. In this case, the OpenDNS IPv6 DNS servers without any filtering are as follows:

• 2620:0:ccc::2
• 2620:0:ccd::2

If you want to use IPv6 DNS with filtering to protect your devices, you will need to use the following:

• 2620:119:35::35
• 2620:119:53::53

Quad9

Quad9 is another service widely used by users who want maximum privacy and security when surfing the Internet. A significant detail is that Quad9 can block DNS resolutions of malicious domains. Therefore, it will protect us against malware, phishing, and other Internet threats. This service also supports DOH and even DOT to provide security and confidentiality to DNS requests and their responses. Depending on the additional services we want, we have different DNS servers.

Malware blocking and DNSSEC validation, typical for most users:

• 2620:fe::fe
• 2620:fe::9

Malware blocking, DNSSEC validation and ECS enabled:

• 2620:fe::11
• 2620:fe::fe:11

No malware blocking, no DNSSEC validation, recommended for advanced users:

• 2620:fe::10
• 2620:fe::fe:10

As you can see, IPv6 addresses are available for the main DNS servers used worldwide. However, you should bear in mind that if your Internet operator provides you with connectivity with this protocol, it will also provide you with its own DNSv6 servers. Bye!

Applications to choose the best DNS for the connection.

There are several DNS servers to use. In fact, some are free and some are paid. For example: 8.8.8/8.8.4.4), Cloudflare (1.1.1/1.0.0.1) or OpenDNS Home (208.67.222.222/208.67.220.220). However, today we will show you some tools to choose the best DNS server available.

DNS Jumper

It is one of the most popular apps for selecting the best DNS. It also allows you to change it automatically from the menu itself. Its way of working is very simple. The tool shows a list with the fastest DNS available in the database.

At the bottom there are some filters. For example turbo mode or mixed mode. This way it is possible to limit the maximum response time. After setting the parameters you just have to click on Start DNS Test. This will start the search for the fastest DNS server for the connection. The result is very complete since it shows the name and the DNS values. Then you just need to configure the connection. You can download it from here.

DNS Benchmark

This tool offers very complete information about DNS servers. In effect, this makes your work take a little longer. However, it is worth the wait. After downloading and running it, you must click on Nameservers. Then please wait a few moments while the server list is loading. Then press the Run Benchmark button.

After a few moments, the tool shows the fastest DNS servers for the connection.

NameBench

This tool has not been updated for a long time. However, it is still widely used when determining the best DNS server. Indeed, it is a very complete application. Since it performs a standard test. But it also uses the browsing history to perform the speed test. In this way it is possible to determine the best configuration for the current location and connection. Please note that the test will take many minutes. A report will be displayed in the web browser after completion. You can download it from here.

DNS Perf

This tool is executed differently. That is, it is not a tool but a web page. Therefore, it is not necessary to download anything, but go directly to the website. In other words, it is a benchmark website that allows you to know which are the fastest DNS servers. Taking into account the location and type of connection.

When visiting the page, a list of DNS servers is displayed. In addition, they are ordered by response time so that you can choose the one with the highest speed. Clicking on any result will show IP addresses, response time and quality of service. An interesting aspect is that it allows you to filter the search by continents.

In this way we have seen how to search for the best DNS for Windows 10. In addition to tools, there is also the option to search directly in the browser. All right, this is all for now. See you next time!

Why change it

There are many reasons to change the DNS in Windows 10. But in reality, the improvement is felt at the level of security and speed. For example, to obtain more speed of navigation, to accede to portals, services and blocked Web pages in our country. In addition, adults can implement a parental control system. Additionally, there are other advantages such as:

• Reliability as they tend to offer greater stability and more real uptime
• Speed that is placed, in some cases, ahead of the operators’ servers
• Security as some offer phishing protection or DNSSEC support.
• Parental control by having options such as filtering access to pages not recommended for minors.
• Skip restrictions to continue accessing domains blocked by the operator.

How to change the DNS from the Windows 10 network configuration

This procedure is relatively simple to do. However, we recommend special attention for novice users. The first thing you need to do is to enter the Windows settings. With this in mind, press the Windows +I combination, once there click on Network & Internet.

The Internet and Networking menu will be displayed immediately. On the right-hand menu, click on Change Adapter Options.

Next you will see the Network Connections section in the Control Panel. Now it is time to select the current active connection. In this example the connection is managed by the Wi-Fi network. Therefore, double click to enter the network properties.

Within the network properties a number of elements are displayed. Please scroll down to get Internet Protocol version 4 (TCP/IPv4). Now click on Properties.

Then follow the next steps. In the first place click on Use the following DNS Server address. Then manually fill in the Preferred DNS Server and Alternate DNS Server options. Finally, check the box Validate settings upon exiting.

Now it is time that everything is in order. With this intention, from a CMD runs the following command:

ipconfig /all

List of the best DNS for Windows 10.

Below I show you the best DNS options currently available. Which can be used as an alternative to those offered by the provider. In addition, they are totally free:

• Level3 – 209.244.0.3 & 209.244.0.4

However, we recommend testing the effectiveness of DNS in the connection. Inasmuch as, a DNS server may be a good option for one person or in one country, and not work as well in other conditions. Indeed, DNS Benchmark, NameBench and DNS Perf are used to locate the fastest DNS. Some also offer additional features such as security and parental control. Very well, this way we have seen how to change DNS in Windows 10. This allows to increase the speed of Windows internet browsing. See you soon.

What is a DNS

Domain Name Servers are responsible for translating web addresses into IP addresses. That is to say, when you enter osradar.com, you enter that address, but the web browser needs another method to know which server to connect to. In other words, when you access osradar.com, the DNS servers translate that text to an IP address. If they don’t exist, then you would have to manually enter all the IP addresses of the websites. This process is done automatically. That is, the user does not intervene in the name resolution. However, the main reason for changing the DNS on your mobile device is privacy. In effect, when you connect through your router’s default DNS, then your identification and your IP is exposed. On the other hand, countries with authoritarian regimes like Venezuela, use DNS to block access to certain critical sites.

So, changing the DNS increases privacy, bypasses blocking and in some cases improves response time on the web.

Changing the DNS in Android.

Once we have seen the utility of modifying the DNS in Android, let’s see how to do it. This is a relatively simple procedure and no external programs are used. First of all, you have to choose a DNS to use. Check here Once we have seen the utility of modifying the DNS in Android, let’s see how to do it. This is a relatively simple procedure and no external programs are used. First of all, you have to choose a DNS to use. Check here a list of free DNS servers. In my case, I will be using Cloudfare’s DNS servers, but you can use anyone you’re comfortable with. Then, just enter the WiFi settings.

Once there, enter the configuration of the network you are connected to, to be able to edit it.

Then enter the IP configuration.

Then change the DHCP setting to Static.

Finally, in DNS 1 and DNS fields, add the values 1.1.1.1 and 1.0.0.1 Then save the changes and wait a few moments while the system reconfigures the connection.

Conclusion

Finally, we have seen how to change the DNS in Android. As mentioned, this action increases the user’s privacy. It is also a tool against government censorship. On the other hand, sometimes it improves the response time of the web pages. This is all for now. I invite you to see our post about Symfony on Windows 10. Goodbye!

What is DNS over HTTPS (DoH)

This is a new security and privacy standard for encrypting DNS requests that run inside the browser. When entering a website, the browser makes a request over the Internet to get the site’s IP address. This is the standard procedure, the problem is that this request is made through a non-encrypted connection. Consequently, an attacker could intercept it and view the website you visit. And what is worse, get the data you are entering causing a security hole for the user. Under those circumstances, is developed, DNS over HTTPS. This is a new security and privacy standard for encrypting DNS requests that run inside the browser. The protocol ensures that the domain name sent to the DNS server makes use of an encrypted HTTPS connection, thus replacing the plain text connection. This prevents an intruder from seeing the sites we are visiting.

How to enable DNS over HTTPS in Google Chrome

Please note that this feature is not yet officially available in Chrome. So it may suffer errors. However, it is possible to enable it on an experimental basis. With this in mind, please copy the following text and paste it into the search bar:

chrome://flags 

In the search field, please enter DNS and then select Secure DNS Lookup.

As you can see the Default value is set. In this case, it means that the protocol is disabled. What we are going to do is modify this value and change it to Enabled.

To make the changes effective, please press the Relaunch button. Once restarted Chrome you can see that DNS over HTTPS has been enabled:

How to enable DNS over HTTPS in Google Chrome by editing the shortcut

Another method that Google Chrome offers us to activate DoH is by editing the shortcut. With this in mind, select the shortcut on the desktop and right-click the mouse to enter the properties:

In the displayed window we go to the tab Direct access and in the field Target we go to the end of the text, leave a space and paste the following:

--enable-features="dns-over-https<DoHTrial" --force-fieldtrials="DoHTrial/Group1" --force-fieldtrial-params="DoHTrial.Group1:server/https%3A%2F%2F1.1.1.1%2Fdns-query/method/POST 

Now, click on Apply and OK to set the changes.

How to enable DNS over HTTPS in Microsoft Edge Beta

The procedure in Edge Beta is very similar to the procedure in Chrome. The first thing you have to do is go to the browser search bar and add the next text:

edge://flags  

From this point on you only have to repeat the same steps as above. For that reason I only attach the corresponding images:

In this way, we have enabled DNS over HTTPS in Edge Beta and Chrome. Now we will be able to use this protocol and surf more securely on the internet. In this globalized world, any additional security measure is very useful. This is all for the moments, before saying goodbye I invite you to see our post about MySQL in Windows 10.

Why this is necessary?

When in a web browser like Firefox we type a web address in the address bar, for example, www.osradar.com it happens that the browser sends a request to the Internet to find out what is the IP address associated with that address. Once it finds it, it will start loading the website.

All this sounds great and it works, but there is one drawback. This request made by the web browser is made using plain text, i.e. without any type of filtering. This causes Internet providers or other people to be able to intercept the request and know which websites you are accessing.

To avoid this, Mozilla has been working for some time on a new feature that allows sending the DNS request as one more HTTPS request and encrypting it. This feature is called DNS-over-HTTPS.

The immediate benefits are the privacy and security of knowing that no one can know which sites you want to access. And this includes your internet provider or cyber thieves.

However, there is one thing to keep in mind. Since this is a very secure feature, it is possible to slow down the loading speed of web pages, but according to Mozilla the impact is minimal.

So, if you like privacy, and want to be a little more secure, you have to enable DNS-over-HTTPS.

How to enable DNS-over-HTTPS?

To be a very important feature, enabling it is quite simple. First, go to the Firefox main menu. This is the button that has the three horizontal bars on the right.

Then click on Preferences.

In the General section, at the end, you will see a button with the Network options. Click on that button.

Scroll down and at the end, you will see the Enable DNS over HTTPS box. There you will see that Cloudflare is the default provider due to the collaboration between this company and Mozilla. Obviously you can change it.

Apply the changes by clicking on the Ok button and you’re done.

This way, now your web browsing is more private and secure. It is expected that soon this feature will be enabled by default in future versions of Firefox.

Conclusion

It is never too much to take extra safety measures when surfing the internet. Therefore, Mozilla implements DNS-over-HTTPS so that our DNS requests are protected against third parties who want to violate our privacy on the network.

For more information, Mozilla’s site for DNS-over-HTTPS is great.
