Among the many complex things that telecommunications have, the DNS may be the only ones that really interest you, even above the IP address Why? Because these are used by internet providers to limit us in a certain way. For example, Movistar uses them to prevent you from seeing websites with pirated content, such as .
For this kind of thing, it’s that Lately, the use of DNS external to Internet providers is becoming very popularand among the many that there are, those of Google are by far the most used and convenient. In addition, anyone can learn about them and take advantage of their advantages.
In this article we will teach you how to configure your network to use Google DNS, whether you use a WiFi or Ethernet connection.. In addition, we will teach you more about these protocols and all the advantages you will have when using those provided by the largest internet company in the world.
What are DNS and what is its use?
DNS is a protocol that is responsible for translating domain names into the IP addresses of the server to which they belong. You may not know it, but when you enter a domain, like for the connection to be effective it is necessary to establish the IP address of said address to the server, otherwise it would not be possible to enter the web.
The problem is that It would be difficult for a person to know each and every one of the IP’s of each one of the webs to which it enters, therefore it is necessary to have an “Intermediary” that is in charge of doing it automatically.
Without the DNS, internet connections would be much slowerand it is possible that domain names did not exist since you would necessarily have to know the IP address, which would make you worry more about this second factor than the first. An example of a world without DNS occurs in , which as you may know is a dystopian version of the internet.
When you download and want to enter one of the many forums of this “parallel universe”, you don’t do it by typing a simple name like , but you must use a series of numbers. What are these codes? Well the IP addresses of each of the Deep Web portalssince DNS does not work in Tor.
The DNS is responsible for knowing the IP of the machine where the domain we want to enter is hosted, and translates it so that communication between servers is effective. For example, Google numeric address is 22.214.171.124 (you can check this yourself by entering this value in your browser’s address bar), but you generally don’t use it because it’s harder to remember than the domain name to begin with.
In addition, these codes may change without prior notice, so you should be aware of each change if you want to continue accessing this search engine. born as a need to translate domain names in 1987 (that’s right, before you had to navigate with codes yes or yes), after several years of failed attempts.
It was devised by Jon Postel in 1983who during the next 4 years of his life would develop this protocol with the help of Paul Mockapetris. So you could say that these two computer scientists are the fathers of the modern internet.
The DNS protocol It is made up of three parts, or rather, phases; the Client Phase 1which works on the user’s computer and is the one who makes the request for the translation of the domain name, the Server, that is in charge of processing the user’s request, and the Authority Zoneswhich are a fraction of the domain name for which the Server is responsible (to translate it into Spanish, the latter corresponds to the subdomains and the extensions .COM, .NET, etc).
How to know that DNS I have working on my computer?
We hope we have not confused you too much with the previous explanation, but now that you know what DNS is, it is time for you to learn what you have on your computer.
This is quite simple and we will teach you how to do it for the main operating systems out there:
To know the active DNS on your computer with Windows 7, 8 or 10, what you have to do is open the “Center network and sharing”. For this you must click on the internet connection icon that is on the far right of the taskbar, either via Wi-Fi or cable.
Once in the network and sharing center you must click on “Change adapter settings”which will open a new window in which you will see each and every one of the possible connections on your computer.
Double click on the WiFi or Ethernet connection that is active on your computer and then on “Details”, which will open a window with all your connection information. You should look at the section “IPv4 DNS Server” to know which are the active DNS on your computer.
View on macOS
In MacOS you can also see your DNS’s easily with a few clicks. What you have to do is enter “System preferences”, where you can see all the configurable aspects of your computer.
Once there you must click on “Net” and later in “Advanced”, This will open a new window where you can see various aspects of your network. What you have to do is position yourself in the section “DNS” and you can see the information you want.
In Android it is easier to do since this is a system that is made to streamline processes. What you should do is pull down the quick settings shade dragging your finger from the status bar at the top of your mobile downwards. Once it is deployed you must make touch and hold it for a few seconds about the option “Wifi”.
*Note: This process may vary depending on the version of Android you have on your mobile device.
This will send you to the WiFi section. The next thing you have to do is a new touch on the option “Settings” which in newer versions of Android is at the bottom of the screen.
Once in this section you will see the DNS in the section “IP adress”, as you can see in the image that we show you below.
Advantages and disadvantages of using Google Public DNS on your computer
Using them Google Public DNS it will have many benefits in your internet connection for many reasons, although depending on the area in which you are, it may not be such a good idea to do, but in Spain for example, it is a more than right decision.
The main advantage why you should consider using Google DNS is because with them you bypass the restrictions that telecommunications companies they impose on various portals for downloading protected content such as , and similar websites. This in turn, it will save you having to which is the second option you have if you want to access this type of portal.
On the other hand, there is the fact that you are They have better support.which allows you expedite response speed of translation requests to servers, making websites load much faster. In addition, these are constantly updated, which considerably improves the security of the Internet connection and protects you from various attacks that reduce the performance of your browsing.
The only downside to using these addresses is that depending on your geographical location, instead of accelerating the loading speed of the websites, it may be slower. However, this is a problem that does not occur in Spain and most Latin American countries.
Steps to set up and connect to Google public DNS
If we have already convinced you enough to change the addresses and use the Google Public DNS, it’s time to teach you how to do it on your own. The reality is that it is a fairly simple process that will not take you more than a couple of minutes. We are going to teach you how to do it in the main operating systems that currently exist.
But before, it is important that you know what the Google Public DNS addresses are:
- Primary DNS:
- 126.96.36.199 (IPv4)
- 2001:4860:4860::8888 (IPv6)
- Alternate DNS:
- 188.8.131.52 (IPv4)
- 2001:4860:4860::8844 (IPv6)
These are the ones that you must enter when the time comes in the explanation that we will give you so that you can apply them in the main operating systems.
Windows is one of the most manageable OS out there, as it makes things much easier for users who are preparing to configure different aspects, especially when it comes to connections.
If you want to apply the changes to the DNS, what you should do is the following:
- Open the “Center network and sharing” in the way that we taught you before.
- Once there, click “Change adapter settings” and then double click on the connection you use, either WiFi or Ethernet.
- Once the window for the network you use opens, click “Properties”.
- When the properties window opens, double click on the option “Internet Protocol version 6”and in the window that opens check the box “Use the following DNS server addresses” and write the addresses that we share with you in the corresponding boxes.
- Then do the same but in the option “Internet Protocol version 4”.
- Now in the properties click on “To accept” and the job will be done.
After that you will have active Google Public DNS addresses in your browser and you will be ready to take advantage of all its advantages.
MacOS is another operating system in which it is relatively easy to make changes at the network server level. To use Google Public DNS, you simply have to follow the steps that we explain below:
- Enter the “System preferences” and then click on the option “Net”.
- Once here you must enter the tab “DNS” and click on the sign “+” which comes out under the default DNS list.
- What you should do here is Change the ones that are by Google and save the changes. With this the work will be finished.
On Linux the process may seem more cumbersome since there is no visual interface as in previous systems, but in general it is quite simple to make changes to the DNS.
What you have to do is the following:
- Open the Linux Terminal and type the command nano/etc/resolv.conf and press Enter.
- After that look for the lines that start with nameserver and move the default DNS 2 lines and write the ones from Google, which in this case will be only the IPv4 ones.
- Once done, press the key combination “Ctrl+O” to save the changes and then “Enter” so that they are overwritten.
On Android or iOS
In mobile operating systems such as Android or iOS it is also very easy to make changes to the DNS of the WiFi networks in which we are connected.
What we have to do is the following:
- Go into “Settings” and locate the section “Wifi”.
- Once there you click on “Advanced Options” and in the DHCP section, look for the default DNS and change them to those of Google.
What public DNS alternatives to Google’s are there?
In addition to Google’s public addresses, there are other companies that offer their own…
