What is a DNS Leak?

Every time you visit a website, your device performs a DNS lookup — translating the domain name (e.g. google.com) into an IP address. By default, these queries are sent unencrypted to your ISP's DNS server.

A DNS leak happens when these queries escape your VPN tunnel and reach your ISP's servers instead of your VPN's private resolver. The result: your ISP can log every domain you visit, even if you think you're protected.

1️⃣

Enable DNS-over-HTTPS

Chrome: Settings → Privacy → Security → Use secure DNS. Firefox: Settings → Network → Enable DNS over HTTPS.

2️⃣

Use Cloudflare 1.1.1.1

Set your system DNS to 1.1.1.1 and 1.0.0.1 — Cloudflare's privacy-first resolver with no query logging.

3️⃣

Use a trustworthy VPN

Quality VPNs route DNS through their own encrypted resolvers, preventing ISP-level surveillance.
