我本地用了 Pcap_DNSProxy 客户端，开了中国大陆白名单代理。检测结果如下：有 Google、OpenDNS 和 Cloudflare 这三个是正常的，其他就不太清楚怎么测出来的……
有人知道检测原理？

大概的思路就是生成大量域名，喂给不同地区的 DNS 服务器，你去测试的时候对比解析结果吧

dns 泄露检测原理应该是自建 dns 服务器，然后将 自己的域名 NS 记录设置为自己的 dns 服务器。
检测时的操作是，js 等方式访问 http://随机编号.自己域名.com 。isp 等 dns 服务器会去访问 检测网站自建的 dns 服务器，dns 服务器根据随机编号就能够对应到具体客户。 |

看 dnsleaktest 下面的说明啊：
The servers identified above receive a request to resolve a domain name (e.g. www.eff.org) to an IP address everytime you enter a website address in your browser. The owners of the servers above have the ability to associate your personal IP address with the names of all the sites you connect to and store this data indefinitely. This does not mean that they do log or store it indefinitely but they may and you need to trust whatever their policy says. If you are connected to a VPN service and ANY of the servers listed above are not provided by the VPN service then you have a DNS leak and are choosing to trust the owners of the above servers with your private data. |
