Reasons to change DNS servers in Windows and navigate fast

What is a DNS and what happens when they do not work well

DNS comes from the acronym in English Domain Name System or Domain Name System. Thus, the task of DNS servers is to go to the address that we write in the address bar of the browser. In case you don’t know, the websites are hosted on web servers with a specific public IP. The moment we put the name of a domain, that DNS server is in charge of providing us with that IP to route the traffic.

Now we are going to see it with a practical example. Write the following IP in the address bar:

216.58.210.163

We will go to the Google website. This happens because the DNS servers are in charge of translating what we write in an IP address. This is done this way because names are easier to remember than numbers.

Why is it advisable to change DNS

Many users use their provider’s DNS. However, we must bear in mind that they are not mandatory to put those, and we can put others. Also, one thing you should know is that you can change both the Windows DNS of our computer or laptop, as well as those of the rest of the devices, such as, for example, a smartphone. The main reason for wanting to change is usually to improve the speed and performance of our connection. On many occasions, the DNS that we use from our operator are not the most appropriate. For this reason, in RedesZone we recommend do not use your provider’s DNS.

The change to a faster and more efficient DNS server will mean that, after writing the url in the address bar, we will have the public IP first, and therefore, it will start to load the content faster. In that sense, if we have problems and want to have more reliability when browsing, a good idea is to change Windows DNS or the devices. Here you have tools to perform performance tests on DNS servers and see which one is best for you to use.

Another factor, no less important, is that we can improve privacy. In that sense we can prevent our provider from tracking us. Thus, we prevent you from collecting information about the web pages we navigate through and creating a profile of us. Nor should we forget about security, since some of them have a filter to prevent the entry of Phishing attacks that can steal our credentials and passwords.

To finish with this section, also using DNS other than those of our Internet provider or ISP can allow us access content that may be blocked in a certain territory. This happens in some countries, when trying to access certain websites and services that may be blocked in that territory.
