===== 部署机场 =====

每秒的IP都变化。采用 simpinvest.eu.org 域名来实现这个机场。

1. 进入 CF => Worker and Pages => create Worker

2. 打开v2ray 添加vlessf服务器，点击生成一个用户id，并复制到脚本的 userID 中去。选择下面其中一个域名，添加到 proxy 中去

五个加速地址
<code | download>
       cdn.anycast.eu.org
edgetunnel.anycast.eu.org
cdn-b100.xn--b6gac.eu.org
     cdn.xn--b6gac.eu.org
 cdn-all.xn--b6gac.eu.org
</code>

3. 保存并部署。然后返回到worker，选择查看，添加一个自定义域名 2207.simpinvest.eu.org （二级域名）

4. 打开地址 <color #ff7f27>''%%0722.simpinvest.eu.org/<userID>%%''</color> 就出现了自己的配置文件

5. 选择网页上的订阅地址，打开v2ray, 从粘贴板导入

<note tip>缺点是ip地址经常变化，会导致google或者其它账号的风控。</note>

        延迟测速线程；越多延迟测速越快，性能弱的设备 (如路由器) 请勿太高；(默认 200 最多 1000)
    -t 4
        延迟测速次数；单个 IP 延迟测速的次数；(默认 4 次)
    -dn 10
        下载测速数量；延迟测速并排序后，从最低延迟起下载测速的数量；(默认 10 个)
    -dt 10
        下载测速时间；单个 IP 下载测速最长时间，不能太短；(默认 10 秒)
    -tp 443
        指定测速端口；延迟测速/下载测速时使用的端口；(默认 443 端口)
    -url https://cf.xiu2.xyz/url
        指定测速地址；延迟测速(HTTPing)/下载测速时使用的地址，默认地址不保证可用性，建议自建；

    -httping
        切换测速模式；延迟测速模式改为 HTTP 协议，所用测试地址为 [-url] 参数；(默认 TCPing)
        注意：HTTPing 本质上也算一种 网络扫描 行为，因此如果你在服务器上面运行，需要降低并发(-n)，否则可能会被一些严格的商家暂停服务。
        如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而 触发临时限制机制，因此才会过一会儿就恢复了，建议降低并发(-n)减少这种情况的发生。
    -httping-code 200
        有效状态代码；HTTPing 延迟测速时网页返回的有效 HTTP 状态码，仅限一个；(默认 200 301 302)
    -cfcolo HKG,KHH,NRT,LAX,SEA,SJC,FRA,MAD
        匹配指定地区；地区名为当地机场三字码，英文逗号分隔，支持小写，支持 Cloudflare、AWS CloudFront，仅 HTTPing 模式可用；(默认 所有地区)

    -tl 200
        平均延迟上限；只输出低于指定平均延迟的 IP，各上下限条件可搭配使用；(默认 9999 ms)
    -tll 40
        平均延迟下限；只输出高于指定平均延迟的 IP；(默认 0 ms)
    -tlr 0.2
        丢包几率上限；只输出低于/等于指定丢包率的 IP，范围 0.00~1.00，0 过滤掉任何丢包的 IP；(默认 1.00)
    -sl 5
        下载速度下限；只输出高于指定下载速度的 IP，凑够指定数量 [-dn] 才会停止测速；(默认 0.00 MB/s)

    -p 10
        显示结果数量；测速后直接显示指定数量的结果，为 0 时不显示结果直接退出；(默认 10 个)
    -f ip.txt
        IP段数据文件；如路径含有空格请加上引号；支持其他 CDN IP段；(默认 ip.txt)
    -ip 1.1.1.1,2.2.2.2/24,2606:4700::/32
        指定IP段数据；直接通过参数指定要测速的 IP 段数据，英文逗号分隔；(默认 空)
    -o result.csv
        写入结果文件；如路径含有空格请加上引号；值为空时不写入文件 [-o ""]；(默认 result.csv)

    -dd
        禁用下载测速；禁用后测速结果会按延迟排序 (默认按下载速度排序)；(默认 启用)
    -allip
        测速全部的IP；对 IP 段中的每个 IP (仅支持 IPv4) 进行测速；(默认 每个 /24 段随机测速一个 IP)

    -v
        打印程序版本 + 检查版本更新
    -h
        打印帮助说明

创建一个worker，取得worker的地址后，v2ray当中添加一个订阅：<color #ff7f27>''%%https://<worker_url>/sub/<优选IP>%%''</color>

  https://scanairport.maiernte.workers.dev/sub/<优选IP>


===== warp+ VPN =====
也是一个永久免费的VPN

===== 资源地址 =====

  * [[https://github.com/ip-scanner/cloudflare|各地的IP]]
  * [[https://github.com/hello-earth/cloudflare-better-ip|优选的IP]]

===== 优选域名 =====
<code >
const proxyIps = ['', '']
let proxyIP =  proxyIps[Math.randow() * proxyIps.length]

// 104 行
url.hostname = 'tv.cctv.com' // 反代伪装网站
</code>

一键扫描自选域名脚本 [[https://github.com/yonggekkk/CF-cdn-domain|原 Gitlab 项目地址]] => [[https://github.com/maiernte/cf-ip-scanner|fork 的项目]]
<code | download>
curl -sSL https://yf3721.oss-cn-hangzhou.aliyuncs.com/raw/CFcdnym.sh -o CFcdnym.sh && chmod +x CFcdnym.sh && bash CFcdnym.sh
</code>

他的脚本和优选域名在serverpai doc 网盘上

====== v2rayU 客户端 ======

省略每次更改设置都要输入密码的方法：
<code>
cd /Applications/V2rayU.app/Contents/Resources
sh cmd.sh
</code>

PAC 设置

  - 使用代理的网站：<color #ff7f27>''%%||xxx.com%%''</color>
  - 不使用代理的网站：<color #ff7f27>''%%@@||cloudflare.com%%''</color> （防止风控）
