What is a DNS leak?

Sometimes a VPN can fail to guard your device’s DNS queries even when the remainder of your traffic is concealed by the VPN tunnel. this is often called a “DNS leak.” If your DNS leaks, unauthorized entities, like your internet service provider or DNS server operator, can see which websites you visit and any apps you employ .

Because of its role because the internet’s address book, DNS affects nearly everything you are doing online. Your browser and other apps use it to seek out the servers that operate the websites and services that you simply believe . Your device sends its queries to a DNS server, and therefore the server sends back directions to what you’re trying to find . this is often what makes DNS a big privacy risk.

What causes VPN leakage of DNS?

DNS leaks can happen for several reasons. Here are just a few:

Your VPN is manually configured. If you’re manually configuring a VPN connection, the danger of DNS leaks is higher and depends on your exact OS configuration. Using the VPN apps will eliminate many of those risks.

An attacker controls your router, like a malicious Wi-Fi operator at a cafe . An attacker could also be ready to trick your device into sending DNS traffic outside of the VPN tunnel. VPN apps offer DNS leak protection, but other apps and manual configurations could be vulnerable.

Manual DNS setup. You (or software on your device) specifically told the OS to not use DNS servers operated by VPN. Power users might require a specific DNS service, except for security reasons, it’s probably undesired for many people.

How can it affect me?

If any of your online traffic goes out through the regular, unencrypted route, third parties may intercept it. that has your ISP or DNS provider, who would be ready to see the websites you visit, the services you employ , and more.

On top of that, you won’t even realize it, unless you’re taking a special DNS test for leaks, just like the one provided here. you’ll call it a VPN security test because if a service won’t fully reroute all of your traffic, it’s not as secure because it should be. That’s why it’s imperative to settle on a VPN with DNS leak protection.
