cloudflare's Issues

一点建议

试用了几个ip,发现几点问题
1.像az sg的那个ip,使用后提示边缘ip不可用。还有好几个ip提示403,nginx setup,抓取失败等,猜测逻辑应该是:curl检测cf网站指定ip,但应该改下,改成curl cloudflare.com 看看内容是否一致,不应该把没指定域名的都扫描进来了
2.不可用ip 希望能够筛选下能够使用的
感谢大佬无私奉献!

about ips

Hi thanks for the ips
is this ips are directed to cloudflare or behind cluoudflare??
if yes why when I open one the ips its not giving me cloudflare 404 error code?

DOH

when i switch to zero trust policy all resets are lost and i can't go back to 1.1.1.1 why is that

请问怎么扫描到这些IP的?

hello,请问怎么扫描到这些IP的,我这边想自己扫描一些距离自建cloud近的IPV6的地址。不知道怎么确认某个IPV6距离某个cloud更近?里面的具体原理或者方法能不能分享一下?

建议增加Ipv6地址,ipv6地址信道没有那么拥堵,还能避免被利用

定义:128bit冒号分16进制

详解:

2001 5-23位 24-32位 33-48位 49-64位
固定开头 regisrty isp prefix site prefix subnet prefix

地址类型: ::设备没有获取ipv6地址

       ::1  类似于127.0.0.1的环回地址

       全球可路由单播地址,globol地址

       无广播地址,无私有地址

本链路地址:fe80,设备直连,设备的直连接口不需要globol地址,自动获取link local地址,利用link local地址就可以进行数据包传递,包括设备启动动态路由协议,路由更新下一跳是link local地址,link local前10bit地址固定为fe80,接着54bit为0,64bit为mac混算

本站点地址:link side ffco,拥有该地址的设备数据包只能在同类地址设备中传递

多播地址:FF0X

泛播地址:anycast,实际为globol地址,一种特殊的应用,允许多个设备共享一个标识,通讯时永远远离终端最远的设备响应

Ipv6包头:ipv6理论不需要vpn,ipv6头部可携带ESP和AH,可以对数据进行加密,ESP和AH就放在下一个头中

接口获取ipv6地址方式:手动配置

                 有状态配置:利用dhcp给接口分配ip

                 无状态配置:不需要dhcp,设备通过mac地址和给予的前缀自己计算

注:配置需设备支持ipv6的icmp,里面有一个ND机制,网络前缀分配
