DNS洩漏檢測
DNS解析器可達性檢測 — 完整的洩漏檢測正在開發中
說明：本工具目前只檢測你的瀏覽器能否連接公共DNS-over-HTTPS解析器（Cloudflare、Google），並不能判斷你的系統實際使用哪個DNS解析器。真正的DNS洩漏檢測需要獨立的萬用字元子網域基礎設施，正在規劃中。
常見問題
什麼是DNS洩漏？
DNS洩漏是指你的DNS查詢被傳送到VPN通道之外，通常傳送到你的ISP的DNS伺服器 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?
You can check for DNS leaks by running this test while connected to your VPN. 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.
