What Is a DNS Leak?

A DNS leak occurs when your device sends DNS queries outside the encrypted VPN tunnel. DNS is the system that translates human-readable domain names like vpnwg.com into IP addresses. Every time you visit a website, a DNS query is made.

When connected to a VPN, all DNS queries should be routed through the VPN tunnel and resolved by the VPN provider's DNS servers. If they leak outside the tunnel, your ISP or a third-party DNS provider can see every website you visit, completely undermining your privacy.

How DNS Leaks Expose Your Privacy

Even with a VPN active, DNS leaks create serious privacy vulnerabilities.

Browsing History Exposed

Your ISP can see every domain you visit, building a complete profile of your online activity even when you think you are protected.

Location Tracking

DNS queries reveal your real geographic location through your ISP's DNS servers, defeating the purpose of using a VPN for location privacy.

Censorship and Blocking

ISPs and governments can use leaked DNS queries to enforce censorship, block websites, or log your activity for surveillance purposes.

How to Fix DNS Leaks

Fixing DNS leaks requires ensuring all DNS queries are routed through your VPN tunnel. Here are the most effective solutions:

1

Use a VPN With Built-in DNS Protection

VPNWG routes all DNS queries through the encrypted WireGuard tunnel to our private DNS servers, preventing any leaks by design.

2

Disable Smart Multi-Homed Name Resolution

On Windows, disable the Smart Multi-Homed Name Resolution feature in Group Policy to prevent DNS queries from being sent on all network adapters simultaneously.

3

Configure DNS Manually

Set your system DNS to use your VPN provider's DNS servers, or use privacy-focused resolvers like 1.1.1.1 or 9.9.9.9 as a fallback.

4

Enable Kill Switch

A VPN kill switch blocks all traffic if the VPN connection drops, preventing any DNS queries from leaking to your ISP.

Frequently Asked Questions

How does a DNS leak test work? expand_more
A DNS leak test checks which DNS servers your device is using to resolve domain names. It sends requests and analyzes the responding servers. If the servers belong to your ISP rather than your VPN provider, it indicates a DNS leak. Our tool checks your connection configuration to detect potential leaks.
Can a DNS leak reveal my identity? expand_more
Yes. DNS leaks can reveal your real IP address and location through your ISP's DNS servers. Combined with browsing history, this data can be used to build a detailed profile of your online activity. This is why it is critical to ensure your VPN prevents DNS leaks.
Does VPNWG protect against DNS leaks? expand_more
Yes. VPNWG uses WireGuard's built-in DNS configuration to route all DNS queries through the encrypted tunnel. Our servers resolve DNS privately, and we enforce a strict no-logs policy. Combined with our kill switch feature, your DNS queries never leak to your ISP.
