DNS problems can cause headaches even if you have experience with web hosting.

It is often difficult to identify where the errors are. DNS can take some time to spread, so sites may appear to be rising or falling at the same time, depending on their physical location.

Do you have DNS problems? Read on to find out how to solve the most common DNS problems and why DNS is so difficult.

Why Domain Name is Not Working

There may be several reasons why your website is not yet displayed. This article is a technical introduction to DNS and name servers, focusing on how they work in the context of web hosting.

If your domain name is not working, it may not be resolved or redirected.

To start, you should check that the following points are not part of the problem :

• The domain has expired and needs to be renewed before it can be reactivated.
• The hosting service associated with the domain has expired.
• Recent name server updates or DNS record updates that have not yet spread.
• Name servers are not configured with the appropriate tab (check in the WHOIS that the correct name servers are listed for your domain).
• Entries placed by the registry or registrar can prevent a domain name from being resolved. If a lock is placed on a domain, it can be displayed in the WHOIS search.

What is DNS?

DNS stands for Domain Name System. DNS is the mechanism that translates Internet domain names, such as example.com, into IP addresses, such as 70.32.68.238.

When you want to visit a website, you usually type something like http://example.com and then expect to see some content in your browser. The content of this website is retrieved from a server located in a data center somewhere – if you are using (mt) Media Temple hosting, we provide the server and the data center. But how does the Internet know to retrieve content from a particular server when you type http://example.com in your browser? The first part of the answer is that the network layer of the internet uses one or more IP addresses to identify each server. The second part is the DNS. The DNS allows domain names to be mapped to these IP addresses so that when you request a specific domain name, the correct IP address is found and the correct server is queried about the content of the website.

The DNS is managed by special servers called name servers or authority servers. The name servers contain a zone file for each domain. The zone file lists the IP addresses that each domain uses for basic web queries, subdomains, e-mail traffic, etc. The zone file is also used to determine which IP addresses each domain uses for basic web queries, subdomains, e-mail traffic, and so on.

Clear your Browser’s Cache

• Open your browser.
• Press Ctrl+Shift+Delete on your keyboard in unison. You can also go to Options>More Tools>Delete Browser Data.
• An options screen will appear. Click the Advanced tab.
• You can select a time range or just leave it as “All the time”.
• Check the boxes next to browsing history, cookies and other site data, cached images and files, and site settings.
• Click the Clear Data button.

Check the Nameservers

Please check whether your name servers are configured correctly or not. You should set up name servers according to the information contained in the hosting account welcome mail that was sent to you during account registration.

Use http://www.whoisresult.com OR http://www.intodns.com to get the details of the current name server.

Check if the A Records are Correct

Verify whether the A record is set up correctly or not. Normally, this setting is configured automatically by the control panel. If someone has updated a manual entry in the A record on the website, this section should be checked.

There is another scenario, for example if you are using different name servers and you do not want to change the name servers. In this case, your A records must be correct and must point to the hosting provider’s A records.

Checking Domain Validity

Make sure that the domain is registered and has not expired; this can be verified using a Whois reference. You can use http://www.whoisresult.com for registration information.

Clearing and Resetting the DNS Cache in Windows

• Open the Run Window dialog box (WinKey + R).
• Type this command in the text box: cmd /k ipconfig /flushdns.
• Click OK.

After executing this command, a console window with a success message should appear. This works on the same principle as removing your browser’s DNS cache. Your operating system also stores DNS information, and your browser will sometimes try to use this cached data if it cannot find DNS information in its cache.
