Detecting which DNS server resolves your queries.

What is a DNS leak?

DNS (Domain Name System) works like the "phone book" of the internet. When you type a website like google.com, your device needs to find the corresponding IP address — and does so by sending a DNS query to a server.

Normally, these queries go to your internet provider's (proveedor de internet) DNS server. This means your proveedor de internet can see every website you visit, even if the connection uses HTTPS.

A DNS leak occurs when your DNS queries escape the VPN tunnel and are resolved by the proveedor de internet's DNS instead of a secure DNS server. Even when using a VPN, your proveedor de internet may still be spying on your browsing.

To be protected, your DNS queries should be resolved by a private DNS server like Cloudflare (1.1.1.1), Google (8.8.8.8), or Escudo VPN DNS — never by your provider's default DNS.

Preguntas Frecuentes

What is a DNS leak?
A DNS leak occurs when your DNS queries are sent to your internet provider's (proveedor de internet) DNS server instead of a secure, private DNS server. This allows your proveedor de internet to see every website you visit, even if you are using a VPN.
How do I know if my DNS is leaking?
Use our free test above. If the detected DNS provider is the same as your internet provider (proveedor de internet), your DNS is leaking. A secure DNS would show providers like Cloudflare, Google, or Escudo DNS.
How do I fix a DNS leak?
The simplest way is to use Escudo VPN, which automatically redirects all your DNS queries through secure, encrypted servers. You can also manually configure a secure DNS like Cloudflare (1.1.1.1) or Google (8.8.8.8) in your device's network settings.
What can my internet provider see with a DNS leak?
With a DNS leak, your internet provider can see every domain you access — websites visited, apps you use, and connected services. This information can be logged, sold to advertisers, or handed over to authorities.
Does a VPN protect against DNS leaks?
Not every VPN protects against DNS leaks. Some low-quality VPNs let DNS queries pass through the proveedor de internet. Escudo VPN includes built-in DNS leak protection, redirecting all DNS queries through secure servers automatically.
