Domain name system, or DNS as it is more often known, is a crucial part of the internet’s database that enables users and regular web users to access websites and other online services using readable and decryptable domain names instead of the more difficult IP addresses.
Nowadays, there are some obstacles that users all around the globe have been facing, and they are exhausted from encountering these problems while browsing. Issues that surround DNS are widely known that are summed up below:-
- Resolution errors – When a user tries to access a specific website, their device needs to hold a DNS lookup to locate the IP address associated with the domain name. Supposedly, if there is an error in the process, the user cannot access the website.
- Cache issues – Servers and client devices maintain caches of DNS records to catalyze the resolution process. But, if the record changes or expires, users may experience website access issues.
- Server downtime- If a DNS server suffers from connectivity issues, users may be unable to access the websites that rely on that server for the DNS resolution.
- Configuration errors- Improperly configured DNS settings can or may cause issues that range from slow website loading times to all-out DNS failure.
That is where the word ‘DNS troubleshooting’ comes into the picture. DNS troubleshooting is considered a process that involves identifying and resolving issues related to the Domain Name System, which is accountable for translating simple human-readable domain names into machine-readable IP addresses. These issues can cause a plethora of websites to become relatively inaccessible or slow to load and can also affect other online services relying on DNS. DNS issues can lead to frustration and even anxiety for users whose entire lifestyle gets disrupted by this.
Fortunately, there are several techniques available for troubleshooting issues revolving around DNS. When troubleshooting DNS issues related to resolution, several steps can be taken to identify and resolve the problem. Here are some standard techniques:
- Use DNS lookup tools: Perform DNS lookups using tools like DNS lookup or dig to identify whether the DNS resolution process is functioning correctly. These tools can help regulate whether a domain name resolves to the correct IP address.
- Check DNS server configurations: Verify that DNS servers are configured correctly and that all necessary records are present. If the DNS server is not configured correctly, it may be unable to resolve domain names.
- Clear DNS cache: Clearing the DNS cache on both the server and client devices can help resolve DNS resolution issues caused by stale DNS records.
- Use alternative DNS servers: If the issue is specific to a particular DNS server, switching to a different DNS server can help resolve the issue. This can involve using a public DNS server, such as Google DNS or OpenDNS, or a different DNS server within the same network.
- Verify DNS configuration on client devices: Ensure client devices are configured correctly to use the affirmative or appropriate DNS server. Incorrect DNS configuration on client devices can cause major DNS resolution issues, even if the DNS server functions perfectly.
- Restart DNS server: Restarting the DNS server can help resolve issues caused by server downtime or connectivity issues and will help you get accustomed to using this technique in the long run.
- Verify network connectivity: Kindly check that there are no network connectivity issues between the client device and the DNS server. In case of connectivity issues, troubleshooting the network configuration may be necessary or mandatory.
Using these techniques makes it possible and easier to troubleshoot DNS issues related to resolution and restore reliable access to websites and online services. If you are facing ‘server DNS Address could not be found error’, ValidEdge recommends this article to fix this problem.
In conclusion, DNS troubleshooting is an essential skill for anyone who relies on internet browsers for work or leisure. While DNS issues can be frustrating, contemplating how to identify and resolve them can help reduce downtime and ensure that websites and online services remain accessible and functional.
