The news appears on the official Google blog and it is worth noting it because it could be a real possibility of making the internet faster and freer . Fast in the sense that websites, from any home or work computer, would open faster than they do now.
Free in the sense that with DNS DNS you can also open sites obscured in a country, censored or limited for various reasons.
Google has indeed opened a new public DNS service .
DNS stands for Domain Name System and to understand what it means just follow a small and simple reasoning.
When you write on the internet address bar of your browser www.navigaweb.net, you enter this website.
Each website is a set of files that resides on a computer called a webserver which is accessible from all over the world.
This webserver has an Internet Protocol (IP) address, similar to that of any computer connected to the internet.
To verify your ip address just go, on Windows, on Start, Run, write "cmd" and then write, on the dos prompt, the word " ipconfig ".
Well, if on my pc there was a webserver with an internet site inside, I couldn't tell you to visit this site by writing stuff like 192.168.57.123 because nobody would remember it!
Here then the DNS servers come into play which are computers with a database of names that associate to each website written in letters (such as google.com or navigaweb.net) the ip address of the web server where the web pages of these sites.
It so happens that, on the browser you can reach any website simply, with words that are understandable and rememberable in mind.
DNS is a network parameter that is automatically assigned by the provider who pays for internet at home.
Each provider has its own DNS server and all the DNS servers in the world share this database for name resolution.
The problem, very little noticeable, may be that the DNS Server of some providers is slower than others to respond and the response speed could affect the speed with which you browse the web and with which you open the websites.
Google Public DNS then allows you to gain speed while visiting websites thanks to the powerful system set up by Google.
An average Internet user like me, during the day, ends up making hundreds of DNS calls and it happens that some more complex pages require more searches on the DNS server database before starting the upload.
This can slow down internet browsing overall.
Google therefore claims to be able to offer a much faster browsing experience for Internet users globally and to make the web faster for everyone .
Another factor related to DNS is that of security because some viruses and malware codes carry out spoofing attacks, that is, they make the computer believe to go on one site while instead ending up on another.
So maybe write Google.com on your browser and end up on sitopericoso.com
Google Public DNS would make spoofing pirates more difficult to modify the interpretation of names and would prevent the viewer of dangerous sites.
Regarding DNS and security, I refer to another article dedicated to the protection on the Internet of children and OpenDNS.
Considering that Google is the real authority of the entire internet network, there is probably to be trusted therefore, if you want to start trying, let's see how to set up the public Google DNS instead of that of the network provider.
In another article the guide to change DNS on Windows PC, Mac and router .
On Windows, on the control panel and look for the icon for network connections.
Among the network connections one should easily recognize the one used which is probably called Connection to the local network (LAN) .
By right-clicking on that icon and choosing " Properties " you access a network configuration tab.
In the properties scroll the list of components to the last one, select " Internet Protocol TCP / IP " and press the property key.
In the tab that opens, you have to go below and press where it says " Use the following DNS server addresses ". To set up the Google DNS, you must write, as primary DNS : 8.8.8.8 and as secondary 8.8.4.4 .
At the end, press OK and then OK again and close the tabs.
If using IPv6, the DNS addresses are instead: 2001: 4860: 4860 :: 8888 and 2001: 4860: 4860 :: 8844
To set up dns on Linux Ubuntu and Mac, refer to the official Google guide.
If you were not convinced, there are software to optimize the internet with faster DNS servers .
To find the fastest DNS servers you can use DNSJumper explained in another article.
