DNS解析器检测
DNS解析器可达性检测：不能检测DNS泄露
说明：本工具只检测你的浏览器能否连接公共DNS-over-HTTPS解析器（Cloudflare、Google），并不能判断你的系统实际使用哪个DNS解析器，因此不能检测DNS泄露。
常见问题
什么是DNS泄露？
DNS泄露是指你的DNS查询被发送到VPN隧道之外，通常发送到你的ISP的DNS服务器 instead of your VPN provider's servers. This exposes your browsing activity to your ISP or other third parties even though you think you're protected by a VPN. DNS leaks are one of the most common privacy vulnerabilities for VPN users.
How do I fix a DNS leak?
To fix a DNS leak: enable your VPN's built-in DNS leak protection, manually configure your system to use secure DNS servers like 1.1.1.1 (Cloudflare) or 9.9.9.9 (Quad9), use DNS over HTTPS (DoH) or DNS over TLS (DoT) in your browser settings, disable WebRTC in your browser, and make sure your VPN client is properly configured to route all DNS traffic through the tunnel.
Does my VPN have a DNS leak?
This page cannot tell you: it only checks that public DNS-over-HTTPS resolvers are reachable and cannot see which resolver your system uses. In a real DNS leak test, if the detected DNS servers belong to your ISP instead of your VPN provider, you have a DNS leak. A properly configured VPN should route all DNS queries through its own servers, so you should only see your VPN provider's DNS servers in the results.
