奇怪🤔，我在进行 smartDNS 改动的时候遇到过，不过是匹配模式选错了，代码级的逻辑我看了下，似乎没问题。

域名匹配方式选 suffix-tree 就会有这个问题，在有主 IPNetworkfile 为 chnroute 的情况下，即使主从域名列表均为空都总是会用主 DNS 查询从而返回被污染的结果。选其它匹配方式没有问题，但是性能降低太厉害。

  "OnlyPrimaryDNS": false,
  "IPv6UseAlternativeDNS": false,
  "WhenPrimaryDNSAnswerNoneUse": "AlternativeDNS",
  "IPNetworkFile": {
    "Primary": "/opt/etc/cn.zone",
    "Alternative": "/opt/etc/empty"
  },
  "DomainFile": {
    "Primary": "",
    "Alternative": "",
    "Matcher":  "suffix-tree"
  },
