The error "DNS server is not responding" shows up when your Web browser unable to connect to the network. There can be many reasons why this error is displayed on your computer monitor: from an un-updated operating system to a misconfigured router. How to fix a bad DNS server depends on what's causing it. In this guide, we will show you the most popular solutions to errors related to the DNS server and we will show you their causes.
What are DNS servers anyway?
DNS is an English abbreviation that loosely translates to "domain name system". This is the process that goes on in your operating system every time you connect to the network - it converts alphanumeric characters only human-readable to computer-readable IP addresses.
Each operation performed using the Internet requires the use of an IP address, which is the result of "transforming" the website's domain name. If this conversion is not possible for some reason, the computer will return a well-known error called "DNS server is not responding".
“DNS Server Not Working” Troubleshooting
There are many ways to get rid of an annoying bug - but first you need to diagnose where the source of the problem is. At this point, it is worth noting that you do not start with the practice of changing the DNS server addressbecause it is an operation that should be done as a last resort.
Causes of DNS server errors
The main causes of errors related to DNS addresses include, among others operating system directory errors, a misconfigured router, or even a non-updated version of the web browser
Check out these solutions first
At the very beginning, it is worth using solutions that may seem trivial at first glance:
Changing the web browser
Start with the simplest thing to do, which is changing your browser and checking if the problem also occurs with your browser - you certainly have more than one web browser installed on your computer.
Disabling the anti-virus firewall
If this does not work, then you will have to change your firewall settings - it is best to turn it off completely while running the tests.
Reboot or reset the router
The last steps are restarting the router (by unplugging it for about 10-15 seconds and reconnecting it) or a complete reset - however, in this case you should be careful as reconfiguring some routers can be complicated.
Alternative DNS server - how to choose a different server?
If none of the above methods has achieved the desired effect, then you will probably need to change your DNS server.
Why? In brief: there is such a thing as a "preferred DNS server" for a given device. Very often it is set automatically by the ISP - but just as often it is also unreliable. In that case, change it manually.
There are many ways to do this, including using the router's internal settings or the PowerShell computer program.
In our opinion, however, the quickest and surest option is to set up a new DNS server with system command line.
DNS addresses and changing them using the Windows command line
To manage your DNS server from the Windows command prompt, just follow the steps below:
- Run the Windows Command Prompt with the keyboard shortcut "windows button”+“r"And enter the command"cmd".
- Enter the following phrase on the command line: “netsh interface show interface". Remember the name that will appear under the section "Interface name".
- Enter the next two commands to the line: "netsh interface ip add dns name = “YourNetworkName” addr = 220.127.116.11 index = 1" and "netsh interface ip add dns name = “YourNetworkName” addr = 18.104.22.168 index = 2", With each field"YourNetworkName"Replace with the name you remember from the second point.
What does it change? Well, from now on, your default DNS servers will be those with the address 22.214.171.124 and 126.96.36.199 - these are the official addresses of the Google platform DNS servers used by the vast majority of devices.
"DNS server is not responding" - you already know how to fix this error
As you can see, in most cases the simplest change of the web browser, anti-virus firewall settings, or router reset is enoughto get rid of the nuisance problem.
If that's not enough - you will have to type three commands into the command line and the error should disappear.
However, if you have done everything in accordance with the above guide and the problem is still not solved - then it makes best sense to contact your internet service provider or mobile computing support.
