This wiki teaches you how to troubleshoot your PC’s Internet connection problems caused by Domain Name Server (DNS) errors. DNS is a server that translates website addresses so that your browser can connect to them. If the addresses are out of date or the server is having problems, a DNS error will occur and you will not be able to connect to a specific site or group of sites, even if you have Internet access. You can fix DNS problems by fixing problems with your current connection, clearing your DNS cache, disabling additional connections, changing your computer’s default DNS server, and even resetting your router.Open DNS is a very good solution! Some people personally use 64.94.1.1 and 4.2.2.4 as primary and secondary DNS servers. It is very rare that you need to search for a domain name on Google or any other browser and select it. This is much more common when using OpenDNS. Go to “Adapter Settings” under “Network” and click “Internet”, then in “Network” select “Sharing” by selecting “Change adapter settings”. Choose your soydin (usually pretty easy to identify), then Properties.You select “Internet Protocol Version 4” and “Properties”. You may find it over there. Ideally, you may need to change your router’s DNS, but this will only work for a specific PC. To find your own DNS servers and evaluate / diagnose your current DNS service, head over to Gibson Research’s website (grc.com) and check out their extremely informative DNS utilities!

Reasons Why You Cannot Connect To The DNS Server

One class of errors is associated with the Domain Name System – distributedthe first name resolution service used by ISPs around the world. Computers running Windows 7, Windows 8.1, and Windows 10 may display the following error messages in the Troubleshooting Found Issues window:

DNS server is not responding 
Your computer is configured correctly, but a device or resource (DNS server) is not responding

When these error conditions occur, the device cannot access the Internet. These DNS server errors can occur for a variety of reasons. You can use the step-by-step network troubleshooting steps to diagnose and fix the problem, as described below.

DNS: Internet Name Resolution

Domain Name System (DNS) is a directory service that translates alphanumeric domain names to numeric IP addresses. As a decentralized process, name resolution usually occurs on networks of DNS servers scattered around the world. Every Internet address that you enter into the search bar of your web browser is then transmitted by your router to a DNS server. This server then converts the domain name to a numeric sequenceand returns the corresponding IP address. If the DNS server does not respond, the desired website cannot be accessed. As a result, you receive a “DNS Server Not Responding” error message.

 

 

What causes a DNS error?

Why am I getting a DNS error? DNS errors are mainly caused by the fact that you cannot connect to the IP address, which means that you may have lost your network or Internet connection. In other words, DNS translates your web domain name into an IP address and vice versa.

What happens if a DNS server goes down?

Once the server goes down, the DNS server should automatically switch DNS A record to point to the IP address of the working server in the first place. When the DNS resolvers come back to query the site’s IP address, they receive an updated IP address and direct the user to the backup server.
