Dns Not Responding

Untitled-1

DNS stands for Domain Name Server. It is a technique that is used to map domain names (such as www.example.com) to their respective IP addresses (such as 93.184.216.119) which cannot be remembered by human beings. When one types a domain name into his\her web browser’s address bar, the computer contacts its current DNS server and asks what IP address is associated with that web address.

The current DNS server which the computer refers to is one’s ISP (Internet Service Provider) DNS server.

The DNS server not responding error takes place when the server never replies back to the web browser’s request. This could happen due to various reasons.

  • The server which host the website might be temporarily down due to technical reasons.
  • The DNS service of the computer is corrupted or not working.
  • The firewall or antivirus itself have accidentally blocked the PC from communicating with a website or certain websites.

DNS server errors are the most frequent type of errors along with 404 error that continuously trouble the web users.

They are a number of ways to rectify this error. Some of them are as follows:-

  1. Reset one’s internet connection by resetting the modem or the Wi-Fi.
  2. Troubleshoot the computer by flushing the cached DNS records, disabling extra connections or by trying a different browser
  3. If the above two steps does not work, reset your router. Try to plug in the computer to the modem directly or to try the alternate DNS server.

The error can be solved in a variety of ways but first we must find the type of the error is it from the above mentioned types:

  1. Try to access the same website under safe mode. If one is able to do so then the error was due to the firewall or antivirus.
  2. If the error is only found on some webpages then the server holding that webpage might be down for some reasons.
  3. If another device connected to the same network can access the same webpage then that means one needs to flush out the cached DNS data from the computer or contact the ISP.
