Sometimes you might have got the error saying “DNS server isn’t responding” when you connect a device to your home network or any other network with internet access. So you get this error when internet connection may fail and there are several other reasons for this error. This error can be fixed by fixing you internet connection, switching off extra connections, flushing with DNS cache, resetting your router, or changing your computer’s default DNS server. In this post, we are going to show you how to fix “DNS server is not responding error” but before we head to the troubleshooting methods we need to understand what DNS is.

What is DNS and Why DNS is not Responding?

DNS in this error stands for Domain Name System. It is decentralized naming system services, computers, and all other resources connected to the internet or any private network. The DNS translates a hostname to IP Address. Let’s take an example of any website. Every site is allocated with an IP address and DNS translates the domain name of the website to IP address. If it weren’t DNS, we would have to remember the IP address of the website with its domain link.

So in simple words, DNS server is a translator of between domain names and IP addresses as it isn’t easier for us to remember numbers than words. Whenever you open a website from your device for the first time then DNS server will remember the IP address associated with the domain name so the DNS request doesn’t occur every time you visit the site that you have visited on the device earlier. So when the internet connection fails you will get the error of DNS isn’t responding.
