分享阿里云 ESA 回源 IP 段
因为阿里云的源站防护功能，在免费版用不了，而我需要在源站设置访问白名单，于是就需要找一份阿里云 ESA 回源 IP 段列表。
Cloudflare和EdgeOne都是公开回源IP段的，同样是属于CDN的ESA居然不公开，有点离谱，不过看样子应该是想作为增值服务，付费才能开源站保护（）
好巧不巧，这段时间基础版ESA都可以免费领取一个月，而基础版ESA是可以开启源站保护的，所以自然也就拿到了回源的IP段列表。虽然文档说这是收敛后的IP段列表，但是得到的回源IP估摸着大概有1700+个，而且我和群友交叉验证过，得到的IP段是一模一样的。应该是收敛之前的完整IP段。估计可能的原因是我没有添加任何要加速的子域名，直接先开源站保护，导致返回了全量的IP段——这是好事啊！连统计和汇总都省了。（后记补充：打脸了，后面进一步测试后发现，免费版和基础版回源IP段是分开的，不用白费力气了）
现在我就分享出来，给需要的站长参考。IP段可以用来设置源服务器的访问白名单，避免源服务器被扫描。具体如何使用，懂得人自然会懂，如果不知道的话，可以看一下这篇文章：
绕过黑洞！利用VPC内网互通低成本实现DDoS攻击下网站高可用中的代理服务器安全组设置（可选）这一小节。
请注意，文中获取到的IP段很有可能是有时效性的，不保证未来可用！获取的时间为2025年12月18日，如果时间过去的太久，需要使用请先验证！
测试后补充：免费版和基础版回源IP段是分开的，所以想白嫖源站保护是不太可能的，后续也不要白费力气了。这篇文章就当作教训挂在这里了。

虽然可能不太用得上，因为有一些VPS/云服务器本身就不支持IPv6，或者是服务器/安全组不支持设置IPv6规则。
不过还是列出来吧。

2408:400a:1010:1e::/64后记补充
后面经过我的测试免费套餐似乎不遵循以上IP段列表，把上面的IP段列入白名单，仍然会导致回源522错误。
经过初步的测试，我发现对于我的网站来说，国内访问进行回源的IP段是163.181.78.0/24这整个C段。
而对于国外的访问情况，则更混乱和复杂，涉及多个IP段，而且随机性较强，较难整理。
看起来阿里云还是精明的很的，生怕你能稳定得到回源IP段，不花钱买基础版，故意把付费的域名设置了专门的回源IP段，然后免费版是另外的段，而且国外回源部分IP变动非常大。
所以，还是老老实实用腾讯的EdegOne吧，或者Cloudflare，因为他们公开了回源IP段。
要么就改成高位不常见端口，隐藏好网站证书等可以识别身份的信息。
