A DNS is a naming method that uses alphanumeric domain names and turns them into numeric IP addresses. Typically, DNS servers act as translators.
“DNS Server Not Responding” indicates that your browser could not authorize a connection to the internet. Typically, DNS errors are created by problems on the user end, whether with a network or internet connection, misconfigured DNS frames, or an outdated browser. They can also be attached to a temporary service interruption that renders the DNS unavailable.
Steps to Determine “DNS Server Not Responding” Error in Windows and macOS
1. Switch to a Distinct Browser
The first move is to troubleshoot the issue by testing your DNS connections. Correcting this problem might be as easy as switching or updating the browser.

To disable IPv6 in macOS, you first require to determine what network interface you’re utilizing. To do this, initiate the Terminal application, then assign the following command:
If you need to disable IPv6 for a wireless connection, you will accept the following directive:
networksetup -setv6off Wi-Fi
For an Ethernet link, you would practice:
networksetup -setv6off Ethernet
Hit the Enter key, and refresh the browser to see if the issue is settled.
10. Change the Default DNS Server on Windows Computer
Start by ticking on the Windows button in the bottom-left corner of the taskbar. Type “Network Connections” in the search field and choose View network connections in the menu that appears.
Choose the internet adapter you’re currently applying—Right-click on the internet adapter, served by Properties.
In the window that opens, pick Internet Protocol Version 4 (TCP/IPv4), and agree on the Properties button.
To manually assign a specific DNS server address, select Use the following DNS server addresses and input the address of an optional server.
You can access Google’s DNS server, which is “22.214.171.124”, under the Preferred DNS server. Then you can attach “126.96.36.199” under the Alternative DNS server and hit OK.
