CloudFlare 自选IP测试

在搭建*2**yN服务器时，因反向代理需要用到CF的自选IP，在网上搜寻发现有很多IP都已失效了。于是自己搞了个代码测试了一下，供大家使用。

首先进入CloudFlare的官方IP list：IP Ranges | Cloudflare

您可以在这里看到CF最近更新的IP地址库。当然，您也可以点击IPv4 text list以及IPv6 text list来查看以txt形式呈现的IP列表。

考虑到IPv4普及度较高，这里就以IPv4进行测试。

把IP地址都复制下来，编辑进代码里：

from ping3 import ping

def p(ip):
    ip_address = ip
    response = ping(ip_address)
    if response is not None:
        delay = int(response * 1000)
        return delay
    else:
        return 2333


l=[
"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",
"172.64.0.0/13",
"131.0.72.0/22",
"104.16.0.0/13",
"104.24.0.0/14"
]

for i in l:
    root=i[:i.rfind(".")]+'.'
    j=0
    while j<=int(i[i.find("/")+1:]):
        j+=1
        b = p(str(root)+str(j))
        if(b==2333):
            print(str(root)+str(j),"×")
        else:
            print(str(root)+str(j),b)

然后慢慢运行。笔者本地的网络运营商是电信，一下数据可供您参考：

其中，IP地址后的数字为ping延迟时间，单位是ms。打×的是ping不通的，可能是被墙了。

值得一提的是，并不是所有能ping通的IP地址都可用作自选IP，笔者测试了几个，如104.24.0.*和108.162.192.*都不可做*2**yN的服务器自选IP。
