问题描述和复现步骤

我在adguardhome入口，上游paopaodns 图片

ttl为0，此时得多刷新几次才能进网站

使用了https://github.com/kkkgo/PaoPaoDNS/discussions/131 自定义递归对接服务器”外包“ 配置如下： 图片

kkkgo commented 3 weeks ago

ttl为0和网站需要刷新多次不一定有联系。 ttl为0是乐观缓存，在ttl过期之后，会设置为0继续提供给下一次，同时请求新记录。 对于绝大多数网站来说，解析记录不是变化非常频繁的，记录可以直接用并且秒开。热门网站只要一直保持有访问，记录就会不断刷新（除非上游响应超时，例如*DoT会消耗更多资源和增加延迟，使用公共DoT DNS的提供商可能会对你的请求进行限速。），在这期间DNS解析记录都会有一个过渡期，不会导致无法访问。 如果是更新比较频繁的比如DDNS记录的网站，可以手动使用RULES_TTL功能或者custom_mod自定义，详情可以查阅文档。 如果你完全不想用乐观缓存带来的好处（不想看到ttl为0），那么你可以在unbound_custom定义：

serve-expired: no
