sing-box

Sing-box默认使用系统DNS，如果Tailscale成功修改系统DNS，可以无需改动Sing-box配置文件

但如果你需要单独配置Sing-box DNS，可参考以下配置：

{
  "dns": {
    "servers": [
      {
        "tag": "dns-default",
        "address": "1.0.0.1",
        "strategy": "ipv4_only"
      },
      {
        "tag": "dns-unlock",
        "address": "100.100.100.100",
        "strategy": "ipv4_only"
      }
    ],
    "rules": [
      {
        "domain": [
          "www.instagram.com", 
          "i.instagram.com",
          "wikipedia.org"
        ],
        "server": "dns-unlock"
      }
    ]
  }
}
