整理CloudFlare CDN全部IP段列表 添加服务器防火墙白名单

如果我们云服务器配置防火墙的话，比如在云服务器上用宝塔面板架设且开启防火墙的同时你还用CDN加速。比如我们有用CloudFlare CDN用于外贸类网站是比较常用的。如果我们同时有开启防火墙，你需要将 CloudFlare CDN的全部IP和IP段添加到白名单。

这里我们需要先找到最新的CloudFlare CDN IP段。

1、CF CDN IPV4

[["131.0.72.0″,"131.0.75.255"],["172.64.0.0″,"172.71.255.255"],["104.16.0.0″,"104.31.255.255"],["162.158.0.0″,"162.159.255.255"],["198.41.128.0″,"198.41.255.255"],["197.234.240.0″,"197.234.243.255"],["188.114.96.0″,"188.114.111.255"],["190.93.240.0″,"190.93.255.255"],["108.162.192.0″,"108.162.255.255"],["141.101.64.0″,"141.101.127.255"],["103.31.4.0″,"103.31.7.255"],["103.22.200.0″,"103.22.203.255"],["103.21.244.0″,"103.21.247.255"],["173.245.48.0″,"173.245.63.255"]]

2、Cloudflare IPv4 CIDR列表

173.245.48.0/20
103.21.244.0/22
103.22.200.0/22
103.31.4.0/22
141.101.64.0/18
108.162.192.0/18
190.93.240.0/20
188.114.96.0/20
197.234.240.0/22
198.41.128.0/17
162.158.0.0/15
104.16.0.0/12
172.64.0.0/13
131.0.72.0/22

然后我们可以根据服务器的设置添加白名单。比如我们可以将添加到宝塔面板白名单防火墙设置中放行这些IP。
