Server equipment representing DNS and secure network routing

Learn what DNS over HTTPS does, what a DNS leak is, and how both affect IP and VPN privacy checks.

What DNS does

DNS translates domain names into IP addresses. When you visit a site, your device usually asks a resolver where that domain points before the connection begins.

What DNS over HTTPS changes

DNS over HTTPS sends DNS queries through an encrypted HTTPS connection to a resolver. This can reduce exposure on some networks, but it does not hide every part of the connection path.

What a DNS leak means

A DNS leak happens when DNS requests go to an unexpected resolver, often outside a VPN tunnel. Your visible IP might show the VPN while DNS still goes to your ISP resolver.

How to check your setup

After enabling a VPN or changing DNS settings, compare your visible IP, DNS resolver, IPv6 behavior, and WebRTC results. Look for mismatched signals.

Frequently Asked Questions

Is DNS over HTTPS the same as a VPN?

No. DoH encrypts DNS queries to a resolver. A VPN tunnels broader traffic through a VPN server.

Can DNS leak when my VPN is connected?

Yes. Misconfigured apps, browser DNS settings, IPv6 routing, or split tunneling can cause unexpected DNS behavior.
