Have you heard of DNS servers ? No? Strange, but you use them every day! They are nothing more than the “translators” that allow you to connect to Internet sites by typing simple, easy-to-remember text addresses instead of long numerical strings, which would be the real coordinates that “find” that site, for example, and allow access to be granted. This means that the use of fast and free DNS servers makes connecting to websites faster than when DNS is slow, in addition to ensuring the possibility of connecting even to inaccessible portals in your region.

Some more details about DNS

Before we move on to the practical part, we separate some additional information about how the DNS works. DNS is first of all a protocol, these three letters that make up its name come from Domain Name System, or Domain Name System. This protocol works by assigning names to IP addresses. For example, the domain is carried out what is called Forward Lookup, direct queries. When you type this address in the search bar of your browser, the DNS server performs a direct search to find the IP address associated with that name. The reverse also happens, the user has the IP address and wants to find the associated name.

If you throw in the search bar of the browser the IP address associated with the name of that website you are trying to access, the page will normally redirect. To find out the IP of a website you can use the ping command in the Windows Command Prompt, for example. For a practical case, type in the ping prompt and press enter. You will discover the IP address associated with that name, and when you type it in your browser, the conversion to the name associated with the address will happen automatically.

Depending on the Internet provider that provides the connection in use, different DNS servers are assigned, in order to guarantee the possibility of surfing the Internet and accessing the various websites for all users who use their services. However, some websites or online services, for various reasons, may not be accessible to standard DNS servers. In addition, standard DNS can always be slower when allowing access to this or that other web page. Consequently, replacing them with others from third parties can be advantageous.

The most popular are those offered by three companies: Google, OpenDNS and CloudFlare.
