Are you facing DNS errors constantly? Finding ways to solve it? Look no further.
DNS (Domain Name System) errors: what are they? We decided to investigate more because this is a frequently asked question. Simply put, a DNS problem happens when a network component cannot correctly connect to another network component. For instance, when a web page name cannot be resolved, an error page rather than the requested site is displayed.
We will describe some of the most typical DNS issues in this article and provide you with the tools to resolve the problem independently, saving you hours of aggravation. Additionally, you’ll discover more about VPN (Virtual Private Network) services and how they help avoid these issues.
Know more about DNS
We should know about the overall operation of the domain name system before delving further into the world of DNS problems.
Every website you visit has a unique IP address that identifies the location of the website’s server. We have human-readable and memorable domain names like google.com and facebook.com for our convenience as these numerical sequences are challenging to recall. The DNS will route us to the correct IP address once we enter these names into the address bar of our browser.
When a website name you specified cannot connect to the required IP address, a DNS error occurs. Instead, you’ll see a notice saying “DNS server not available.” Unfortunately, there are many moving pieces in this process, so it isn’t always obvious what’s wrong. Your router, browser, computer, ISP (Internet Service Provider), or the DNS servers, for instance, could be the cause of the issue.
As you can expect, to identify the root of the problem, you’ll need to troubleshoot every component. Your router will need to be restarted throughout this procedure, and a different web browser will be tried. Don’t worry; we’ll give you some advice to make the procedure easier.
Here’s Some Quick Fixes of DNS Error
Here is the procedure we advise you to follow to identify the cause of your DNS annoyances.
- Restart your computer or other device: Every internet user who is tech savvy is aware that turning something off and on again typically solves problems. This life hack does not exempt DNS problems. Try your browser first, followed by your web-surfing gadget.
- Shut down the router: Your home router is most likely the next offender. Once more, most problems may be fixed with a simple restart.
- Change your browser: If your default web browser keeps failing, think about trying a different one.
- Switch off your firewall: Your firewall or antivirus program may try to protect you by causing DNS difficulties. See whether the issue is fixed by temporarily disabling them.
- Clear the cache on the browser: Browsers have the ability to save data to speed up website loading times. However, if the website recently renewed its IP address, this could work against you. To get rid of any obsolete data, clear the cache in your browser.
- Switch off other connections: P2P, Bluetooth, and other connection types could obstruct your browser’s or internet connection.
- Streamline your software: Ensure that all the puzzle parts (your device, browser, and network drivers) are in place and current.
- Verify the DNS settings: In order to make sure there are no configuration errors, the final step entails reviewing DNS settings and addresses. Depending on your device, network configuration, and ISP, specifics may change.
What is a DNS leak?
A DNS leak, in its simplest form, is a security hole that exposes your DNS requests and makes them visible to your ISP and other unauthorized snoopers. These observers might be keeping track of the data indefinitely for future use.
How to Prevent DNS Errors?
Not to mention how DNS issues related to online privacy and virtual private network services would be negligent. To be more specific, VPN users should educate themselves on DNS leaks and how they can compromise your attempts at anonymity and geo-unblocking.
Fortunately, there are a few trustworthy methods to guarantee the confidentiality and security of your DNS requests:
- Utilize a reliable VPN like ExpressVPN
- Use the DNS servers from Cloudflare
- Use private browsing tools
- Turn off DNS using a firewall
- Of course, using a tried-and-true VPN, like NordVPN, is our top suggestion. It will stop DNS leaks and encrypt all of your internet traffic with AES-256. A VPN also offers other advantages like removing geographical limits and protecting your data privacy.
Additionally, since the VPN service will take care of any DNS errors, you won’t need to worry if it is reliable.

When utilizing a VPN, the VPN will adjust the DNS settings to the current circumstances. If a DNS problem happens, you will hardly need to change them manually.
We trust you found this information useful in understanding and resolving DNS difficulties. The key message here is that you should always check to see if the DNS server is delivering the same response even when used from different locations when there is a DNS error. Additionally, it is crucial to make sure the domain name is active and that a reliable ISP is always in place.
But let’s say the problems are with the infrastructure of a business. In that scenario, rather than attempting to resolve the difficulties yourself, we strongly advise contacting a specialist who will do so effectively, preventing any potentially devastating repercussions, such as hackers compromising security.
However, resolving DNS errors at home could be more challenging, particularly if you’re not an expert in networking. The best course of action in that situation is to merely utilize a paid VPN service.
In this manner, the software will automatically resolve any VPN DNS difficulties. A VPN like ExpressVPN, also enables you to change your location and secure your online data, among many other advantages.
