What is DNS leak?

Awareness about digital privacy has been on an all-time high for a while now with Edward Snowden and other such whistleblowers coming to light.

One of the most basic and yet essential aspects of safeguarding your privacy is using a Virtual Private Network (VPN). However, even when you’re using a premium VPN service, your DNS queries can still be exposed.

A DNS leak happens when your computer or device leaks information about which DNS server it is using. This can happen when your VPN is not properly configured or if there is a flaw in the VPN’s software.

This means that anyone monitoring the traffic passing through your network could see which websites you are visiting and even get your IP address. This could potentially expose your identity and personal information.

How do I know if my DNS is leaking?

With DNS Leaks, your ISP can see what you are doing online. This might include things like where you’ve been browsing or who you have contacted through email. It also includes the websites that you visit and any information that is sent to these sites too.

While there are many companies out there offering different solutions for users looking to keep their DNS traffic private, not all of these solutions are created equal. In this blog post, we will discuss how to determine if your DNS is leaking and some tips on how to protect yourself from such leaks.

The best way to determine if your DNS is leaking is by using a tool like ipleak.net. This website will tell you if your DNS is leaking and will also show you the IP address of every website that you visit. In most cases, this information can give away a lot about who you are as an online user. To combat those leaks from being so accurate, the best way to find out if there’s a leak in your network is by using a VPN.

A VPN, or Virtual Private Network, is a service that allows you to connect to the internet through another server. This other server acts as an intermediary and helps keep your identity and location hidden from the websites that you are visiting. By using a VPN, you can help ensure that your DNS traffic remains private and does not fall into the hands of your ISP.

There are many different VPN services available on the market, and it can be difficult to determine which one is right for you. When you visit your favorite websites, your computer asks your ISP DNS resolvers to identify that site's IP address, so you don't have to remember them all personally. 

What does a DNS leak test do?

A DNS leak test checks to see if your computer is leaking information about which websites you visit. This can be a problem because it can allow other people to track what you're doing online. A DNS leak test can help you protect your privacy by identifying any leaks and fixing them.

There are a few different ways to do a DNS leak test. One way is to use a website that specializes in testing for leaks. Another way is to use a tool that comes with your operating system or browser. Finally, you can also check your router's settings to see if there are any leaks.

No matter which method you use, it's important to remember that a DNS leak test is only effective if you actually fix any leaks. So make sure you take the time to do some research and understand how everything works before you start changing your settings or reconfiguring your router.

Types of DNS leak

When the internet was in its infancy, it may not have been used for much. These days, however, virtually everyone uses it in some way or another; whether that's simple to browse websites and social media platforms like Facebook and Twitter – which most people cannot do without these days – or if they're using more advanced methods such as online banking and shopping.

Naturally, with so many people using the internet for everything from communicating with friends and family to managing their finances, it's become a prime target for criminals and hackers who want to exploit users in any way they can. One of the most common ways that criminals and hackers manage to access users' personal data is through something called a DNS leak.

There are a few different types of DNS leak, which we will go over below.

– Local DNS leak: This is when your computer sends requests for domain names to its own local DNS server rather than the one provided by your VPN service.

– Global DNS leak: This is when your computer sends requests for domain names to servers outside of the VPN tunnel.

– DNS leak through WebRTC: This is a potential leak that can occur when using browsers that support WebRTC, such as Chrome and Firefox. It allows for direct communication between devices without going through a middleman, like a VPN server.

To protect yourself from DNS leaks, be sure to use a VPN service that offers DNS leak protection. This will ensure that all of your traffic is routed through the VPN tunnel and not exposed to outside servers.

How do I fix a DNS leak?

DNS leaks can be a serious security issue, but they're also easy to fix. Here's how to do it:

First, check whether you have a DNS leak or IP leak. To do this, use the

DNS Leak Test website. If your IP address is displayed on the website, you have a DNS leak.

Now, you need to fix your DNS leak. To do this:

Log in to the router settings for your network and change the primary and secondary DNS servers under Internet Connection Settings to a non-logging provider such as Cloudflare or Google Public DNS that will not log any of your browsing data. If you're using Windows or Mac, simply click the network icon in your system tray and change it there.

You can also use a VPN to fix your DNS leak. A VPN will encrypt all of your traffic, preventing anyone from seeing what websites you're visiting.  Use your own DNS resolving server.

If you're not sure which VPN to choose, we recommend NordVPN. They have a strict no-logs policy and over 5000 servers worldwide, making them perfect for streaming and browsing. You can get a NordVPN subscription for as little as $69 per year.

To fix your DNS leak, you can:

– If you're using Windows or Mac, change the network settings on your router

– If you're using a router, change the DNS settings on your router to use non-logging providers such as Cloudflare or Google Public DNS.

If none of these options work for you, contact support and we can help! ISP DNS servers are exclusively great with VPN service and DNS requests for setting DNS servers. The internet service provider with IP addresses can disable DNS servers for the right VPN connection. ISP DNS server will help you resolve the options precisely.
