DNS leaks can reveal your real IP and location, even if you're using proxies, VPNs, or antidetect browsers. Use Pixelscan to check if your DNS queries are leaking to your ISP and compromising your setup. Fast, accurate, and no setup needed.
How does a DNS leak test work?
A dnsleaktest works by forcing your browser to resolve a set of domain names. The test tracks which DNS servers respond to those requests. If the results show DNS servers from your ISP or a location you’re trying to hide, you have a leak. Our tool makes it easy to check DNS leaks in seconds.
Why should I check for DNS leaks?
If you're using a VPN, proxy, or antidetect browser, a DNS leak check is critical. A leak exposes your browsing activity and real IP to your ISP, government, or any monitoring party—defeating the purpose of privacy tools. You should regularly check DNS leak status to stay secure.
What causes a DNS leak?
- Misconfigured VPN or proxy settings
- VPNs that don’t route DNS through encrypted tunnels
- Operating system defaults that override VPN DNS settings
- IPv6 or WebRTC-related traffic
- Malware or DNS hijacking
- Antidetect browsers that leak or use system DNS
What are the risks of a DNS leak?
- Tracking by platforms or ISPs
- Account bans from IP/DNS mismatches
- Linked accounts and lost anonymity
How do I fix a DNS leak?
- Use a VPN that forces DNS through its own secure servers
- Set your system DNS to a trusted provider (e.g., Cloudflare, OpenDNS)
- Disable IPv6 if your VPN or setup doesn’t support it
- Clear your DNS cache to remove old entries
- Regularly run a dns leak test to ensure your real IP isn’t exposed
Do DNS leaks affect users of antidetect browsers?
Yes, especially. Antidetect browser users depend on full anonymity across multiple layers, including DNS. If DNS requests leak to your ISP, platforms can detect a mismatch between your browser fingerprint and network origin. A DNS leak test helps ensure you aren’t revealing your identity unintentionally—even if your user agent and browser profile are spoofed.
