Common Causes of DNS Errors on Computers
DNS Errors on Computer
DNS errors on computers can be frustrating and can cause a lot of inconvenience. DNS stands for Domain Name System, which is responsible for translating domain names into IP addresses. When you type a website address into your browser, the DNS server translates the domain name into an IP address, which is then used to connect to the website. If there is an error in this process, you will not be able to access the website. In this article, we will discuss the common causes of DNS errors on computers.
One of the most common causes of DNS errors on computers is incorrect DNS settings. If your computer is not configured to use the correct DNS server, it will not be able to translate domain names into IP addresses. This can happen if you have recently changed your internet service provider or if you have manually changed your DNS settings. To fix this issue, you need to check your DNS settings and make sure they are correct. You can do this by going to your network settings and checking the DNS server address.
2. DNS Cache
Another common cause of DNS errors on computers is the DNS cache. The DNS cache is a temporary storage area on your computer that stores the IP addresses of recently visited websites. This helps to speed up the process of accessing websites as your computer does not have to translate the domain name into an IP address every time you visit a website. However, if the DNS cache becomes corrupted, it can cause DNS errors. To fix this issue, you need to clear your DNS cache. You can do this by opening the command prompt and typing “ipconfig /flushdns”.
3. Firewall Settings
Firewall settings can also cause DNS errors on computers. If your firewall is blocking the DNS server, your computer will not be able to translate domain names into IP addresses. This can happen if you have recently installed a new firewall or if you have changed the settings of your existing firewall. To fix this issue, you need to check your firewall settings and make sure that the DNS server is not blocked.
4. Malware or Virus
Malware or virus can also cause DNS errors on computers. Malware or virus can infect your computer and change your DNS settings, which can cause DNS errors.
