段落1、需求

服务器的IPv4看Netflix，没希望，被Netflix的IP地址库封的死死的，手里有一台服务器，它的IPv6地址是英国的原生IPv6，可以支持观看Netflix

那么，就简单了，我们通过配置让Netflix的流量走到IPv6出口即可

入站的流量通过服务器的IPv4地址进入，出站的Netflix流量通过原生IPv6出站，其余非Netflix流媒体的流量，还是通过IPv4出站

通过 基于sjlleo/netflix-verify，检测VPS服务器IP地址或节点IP是否支持Netflix流媒体 2022-2-28

段落2、部署操作

操作1-3

// 在routing的rules列表中增加Netflix的相关域名,指定它走IPv6的路由

  "routing": {
    "domainStrategy": "IPIfNonMatch",
    "rules": [
      {
        "type": "field",
        "domain": [
          "netflix.com",
          "netflix.net",
          "netflixdnstest1.com",
          "netflixdnstest2.com",
          "netflixdnstest3.com",
          "netflixdnstest4.com",
          "netflixdnstest5.com",
          "netflixdnstest6.com",
          "netflixdnstest7.com",
          "netflixdnstest8.com",
          "netflixdnstest9.com",
          "netflixdnstest10.com",
          "netflixinvestor.com",
          "netflixtechblog.com",
          "nflxext.com",
          "nflximg.com",
          "nflximg.net",
          "nflxsearch.net",
          "nflxso.net",
          "nflxvideo.net",
          "geosite:netflix"
        ],
        "outboundTag": "IPv6_OUT"
      },
      {
        "type": "field",
        "outboundTag": "IPv4_OUT",
        "network": "udp,tcp"
      }
    ]
  },

操作2-3

// 在入站的inbounds中增加"sniffing"的参数

  "inbounds": [
    {
      "sniffing": {
        "enabled": true,
        "destOverride": [
          "http",
          "tls"
        ]
      },
      "settings": {
        "clients": [
          {
            "id": "dc0d52a2-c6c3-44e4-85cf-b479f736c378",
            "alterId": 0
          }
        ]
      },
      "port": 8080,
      "protocol": "vmess"
    }
  ],

操作3-3

// 在outbounds出站中区分开IPv4/IPv6两项内容

  "outbounds": [
    {
      "protocol": "freedom",
      "settings": {},
      "tag": "IPv4_OUT"
    },
    {
      "protocol": "freedom",
      "settings": {
        "domainStrategy": "UseIPv6"
      },
      "tag": "IPv6_OUT"
    },
    {
      "settings": {},
      "protocol": "blackhole",
      "tag": "blocked"
    }
  ]

段落9、额外信息

同理，一些主流的支持IPv6的网站，也可以根据这个办法，进行IPv6分流

"geosite:netflix"
"geosite:google"
"geosite:youtube"

还有一种方式备用，sni+dnsmasq 分流

搭建完后，修改配置/etc/sniproxy.conf，设置ipv6优先，完重启机器

resolver {
    nameserver 8.8.8.8
    nameserver 8.8.4.4 # local dns should be better
    mode ipv6_first
}
