When you type in a website address, your computer relies on the Domain Name System (DNS) to translate that human-readable address into a numerical IP address that the internet understands. However, sometimes the DNS server may not respond, resulting in an inability to access websites.
When this issue occurs, it could be due to several reasons, such as a network problem, misconfigured DNS settings, or a problem with the DNS server itself. To troubleshoot this issue, you can try restarting your router, flush the DNS cache on your computer, or change your DNS server settings to a public DNS server like Google’s (8.8.8.8 and 8.8.4.4) or Cloudflare’s (1.1.1.1).
If these steps do not resolve the issue, it’s advisable to contact your internet service provider or IT support for further assistance. Remember to also regularly update your software and security settings to prevent any potential DNS server not responding issues in the future.
