我在家用网络中使用自己的DNS服务器过滤广告，但是在开始运行DD@H之后，DNS服务器的日志数据库开始膨胀了起来，检查后，发现运行DD@H的设备非常频繁地请求B站直播相关的域名。
经过一段时间的测试，我发现程序运行一天，DNS服务器上增加了约2.9万条相关域名的查询记录。这严重拖慢了DNS服务器的响应速度，并导致闪存设备的快速损耗。
请问有没有可能在DD@H中增加缓存DNS查询结果的方法，以减少这种频繁重复DNS查询的现象？

奇怪 我用的方法应该没有跳过操作系统的DNS缓存之类的 hummm

请问操作系统？

"Debian GNU/Linux 10 (buster)

主楼的那张图是在发现问题之后，在本地架设测试用dns服务器的数据统计截图。
话说linux有DNS Cache吗，Windows是有DNS 缓存的🤨

v1.8.0release里问题还是存在，对api.live.bilibili.com的请求大概5秒发生一次。
