-# better-cloudflare-ip
-shell脚本，适合中国大陆用户查找适合自己当前网络环境的优选cloudflare anycast IP
+## 感谢
+
+本项目Fork自 <a href="https://github.com/badafans/better-cloudflare-ip" target="_blank">badafans/better-cloudflare-ip</a>
+
+感谢 badafans 提供 Cloudflare Anycast 节点汇总
+
+## 使用申明
+本项目侧重于研究任播技术中丢包率与网速的相互关系，仅供学习使用
+
+### 禁止使用范围准则如下
+
+a) 相关机构提示网页有威胁的，有非法信息提示的网站。
+
+b)医院类型网站（流产，皮肤病，性病等医院），未获得卫生部资质的网站。
+
+c)网站主体内容含有色情（视频交友，一夜情交友）、违法（办假证，贩卖仿真枪）、封建迷信、游戏私服、游戏外挂、网赚、两性、美女贴图和动漫贴图（尺度过大）、赌博（含贩卖赌博工具。）、博彩等内容。
+
+d)网站存在恶意流氓广告（存在非法内容视频链接，非法网页内容链接）。
+
+e)网站存在任何破坏或试图破坏网络安全的行为，以病毒、木马、恶意代码、钓鱼等方式，试图对网站、网络相关软硬件进行恶意扫描、非法侵入系统、非法获取数据等内容。
+
+f)网站内容存在版权风险的网站（视频，小说，音乐等网站）。
+
+g)网站含有药品销售、保健品销售，但未取得资质的，或严重夸大药效事实。
+
+h)网站主要业务为向非法网站提供支付、交易平台、担保，代理外国金融理财（炒股，炒现货，炒黄金）等服务的网站。
+
+i)网站中大量存在影响社会和谐稳定的内容的网站（涉嫌攻击国家，攻击领导人，攻击人民，言论煽动性质网站）。
+
+j)网站内容含有国家相关法律法规不允许的其他内容。
+
+k)网站内容含有VPN，网络代理等内容。
+
+l) 通过技术手段或非技术手段干扰Cloudflare所有产品正常运营的网站。
+
+m)网站内容为发布虚假不实消息行为，或侵害了他人的合法权益行为的网站。
+
+n) 获取网站内容需要通过登录等方式，无法直接查看造成内容无法审核的网站。
+
+o) 提供影视、软件和应用等下载服务的网站。
+
+## 介绍
+
+* 用 Python3 重写了测试脚本；
+
+* 使用多线程优化 Ping 测试，大大缩短测试时间；
+
+* 不再设置测速阀值，而是择优选择数个 IP 进行速度测试；
+
+* 新增通过 anycast IP 进行原始服务器测速，获取真实下载速度；
+
+## 说明
+
++ 继续使用 <a href="https://github.com/badafans/better-cloudflare-ip" target="_blank">badafans/better-cloudflare-ip</a> 项目中的 curl 和 fping 工具
+
++ 需要安装 Python3 （Windows / Linux 通用）
+
++ 通过 pip3 安装 requests
+
++ 在原始服务器的网站根目录下生成测试文件
+
+    + dd if=/dev/zero of=cf_speed_test bs=1M count=100
+    
+    + 要能以 https://(cf中分配或者解析的域名)/cf_speed_test 访问并下载
+    
+    + 测试下载速度时将进行 15 秒的下载操作
+
++ 在脚本中配置 original_host 参数
+
++ 运行脚本进行测速
