DNS server not responding – How to fix the error

One of the actions that we carry out the most on a daily basis with our computer is surfing the Internet. This task should not be more complicated as long as we have enabled the connection with our provider. However, on occasion we may come across an error message that we do not know how to act on. This may be the case with the DNS server is not responding” error.

In the event that this error suddenly appears, we will not be able to access any website through the Internet. That is why today we are going to see what exactly the DNS server is, the reasons why this error may appear and, most importantly, what we can do to solve it.

DNS server not responding

What is the DNS server

The domain name system (DNS) can be considered as the telephone book of the Internet and is in charge of converting numerical addresses or IPs into domain names . Its purpose is to translate what a user types into their browser into something a computer can understand and use to locate a website. In this way, when we write a domain name like Google.es in our web browser, the DNS is in charge of finding the correct IP address for this site. Subsequently, the browser makes use of this address to be able to communicate with the origin servers in order to be able to access the information on the website. So we can say that all this happens thanks to the DNS servers.

Reasons why this error appears

There are occasions where we can find certain DNS error messages when accessing a website and one of them is the message “The DNS server is not responding”. This means that our web browser is not able to connect to the site because the DNS server cannot correctly map hostnames to IP addresses.

There is no single cause for this error, as the reasons can be anything from bad network adapters to bad server addresses. It can also happen that the servers are saturated , we do not have a good Internet connection or that there is simply a problem with the router. Furthermore, it may also be due to a problem with our antivirus software .

Fortunately, most of these problems can be solved without much effort, but since there is no single cause, we may have to try different ways until we find the one that can solve the problem.

We wait about five minutes for both the router and its network to shut down properly. Later we turn it on again and check if this ends the problem.

Change the DNS server

Another simple solution to solve this error is to manually change the DNS server. Through this action we will be able to get around the limitations and we can even obtain a better Internet browsing speed from our device. To do this we must change our DNS server to a known, fast and public DNS.
