关于 sing-box 的规则问题咨询下大家， dns 和 route 规则为什么不同步？

[shangnengfanfo]

国内小众站都走代理了，看日志 dns 模块是触发 geoip-cn 这条规则了，但是 route 模块直接走 final ，好奇为什么不会经过 route 内的 geoip-cn 规则走直连呢？

域名请求不会进行 IP 匹配

[yellowvii]

@yellowvii #1

这个行为可以通过配置改变

延伸阅读： https://sing-box.sagernet.org/configuration/shared/listen/#domain_strategy

domain_strategy

One of prefer_ipv4 prefer_ipv6 ipv4_only ipv6_only.

If set, the requested domain name will be resolved to IP before routing.

If sniff_override_destination is in effect, its value will be taken as a fallback.

[shangnengfanfo]

@yellowvii 前一句很好理解，后面这句没怎么懂——如果 sniff_override_destination 生效，它的值将作为后备。

[yellowvii]

@shangnengfanfo #3 我理解同时配置两者，sniff_override_destination 的优先级高

[shangnengfanfo]

@yellowvii 已经用上了，目前运行良好，非常感谢！！！
singbox 是好东西，就是它的文档一言难尽

[belldasd]

@shangnengfanfo 请问具体怎么修改配置？

[shangnengfanfo]

@belldasd "domain_strategy": "prefer_ipv4", 把这个加进去就可以了

[belldasd]

@shangnengfanfo 谢谢！我去试试看。
