From 2017 until now, the concept of DNS, and more specifically Google's DNS, has aroused the interest of a large part of the users who browse the Internet. The term DNS is defined, according to Wikipedia, as the transcription of Domain Name System, or what is the same, Domain Name System. But what are DNS? And more specifically, what are Google DNS and how can we use them? We see it below.
What are DNS?
A DNS is defined in computing as a nomenclature system whose functions are limited to translating the IP addresses of the different websites. It is well known that each web page has a public IP address so that it can be accessed from Google . A DNS is precisely responsible for translating those IPs into an address easier to remember. For proof, the image below.
Your expert has the IP address 18.104.22.168 . A DNS is responsible for translating that same address to Tuexperto.com so that anyone can access it from search engines such as Google or Bing.
In fact, by typing that same address in the browser we will be able to access Your Expert without any major problem, as we can see in the image above.
What are Google DNS and what advantages do they have?
By default, most routers usually come with a series of DNS preconfigured by the operator on duty (what in computer science is called ISP). On occasions, these DNS tend to coincide with those of the company (Movistar, Jazztel, Vodafone, Lowi ...). Unfortunately, most of these leave a lot to be desired when it comes to translating and indexing IP addresses to public domain addresses. In terms of security, they are also susceptible to hacker attacks.
This is precisely the reason why Google decided in 2009 on a list of its own DNS. It did so in order to speed up the loading of the linked pages from the browser itself. But how does Google get its DNS to be faster than our operator's? Easy. Being one of the largest companies in the world and the leading search engine, it has an up-to-date list of virtually every web page .
In addition, its multiple servers hosted throughout the globe allow them to redirect from our computer to the closest server, which may be in Madrid, Barcelona or one of the most important cities in our country. In companies like those mentioned above, it is usual for these same redirects to be made to servers outside of Spain , with all the response time that this entails.
How to use Google DNS in 2019
At this point, the question is obliged, how can I connect to Google DNS? Depending on whether we are on a computer or mobile, the process may vary from one device to another.
Change DNS in Windows
If we have a Windows computer, the process is very simple
The first thing we should do is open the Control Panel and go to the Network and Internet section . Then, we will go to the Network and Shared Resources Center to finally click on our WiFi or Ethernet connection.
Then a window will open with the name of Ethernet (or WLAN) status. We will click on Properties and click on Internet Protocol version 4 to click on it again and click on the Properties option.
Finally, we will click on Use the following DNS addresses and we will write the Google DNS addresses that we will see below in the two boxes (we will have to write the same address in both the first and second boxes).
Change DNS on Android
The process on Android is even easier than on Windows.
To do this, we will go to the Network and WiFi Settings within the Android Settings and we will press the network to which we are connected.
Then we will click Modify network and look for the two boxes of DNS 1 and DNS 2.
Finally we will write the two Google DNS addresses (we must write the same one in the two boxes).
