A detailed guide to learning more about DNS servers, how do they work, as well as methods to fix DNS errors, including DNS Probe Finished No Internet error, and DNS Failed To Load error.
If there is any reason that all DNS servers around the world are shut down, I’m sure that all of us will not be able to visit any websites via certain domain names. The Internet is still accessible, but only through IP addresses, like 18.104.22.168 or something similar
DNS servers are barebone of the Internet. Its job is act like an address book, which will match all domain queries to correct IP addresses. As for instance, the IP address of www.google.com is 22.214.171.124. However, your computer doesn’t know that even you don’t know that. This record stores in an appropriate DNS server.
How Does DNS Server Work?
When you type www.google.com into the address bar of your browser and press “Enter” - it will start sending a request to DNS server and then the DNS server will return with a right IP address. From the result, your browser will load the contents of the website from the returned IP address.
It took several minutes to explain how does DNS server work. In fact, the process only takes a few seconds, based on the speed of the Internet connection. If the speed is fast enough, it might only take one or two seconds.
As I mentioned, DNS servers are barebone of the Internet. So if there are any errors with these DNS servers, you will not be able to access the Internet. Sometimes, due to some specific reasons, these DNS servers are unresponsive and don’t react any of your requests. In this case, you may receive DNS errors on your PC or browser, depending on the cause of them. However most cases, it will tell you that DNS server does not respond. It is one of the standard DNS errors, along with “DNS probe finished no internet”, or “DNS failed to load”.
In the past, I have encountered these errors many times. Most of them occur due to DNS servers don’t respond. If you can replace DNS servers on your PC or device with another one, I’m sure you can avoid future DNS errors.
There are many third-party DNS servers that you can quickly find on the Internet. I would recommend you and your friends to use Google’s DNS or OpenDNS. Both are excellent third-party DNS server services that provide the best quality, good speed, as well as very stable.
Of course, you can easy to find many other third-party DNS servers from Google.com with search terms “list of best DNS servers” – but Google’s DNS and OpenDNS are both recommended services from me. And I think many other experts will also recommend you to use these services.
