希望可以添加一个自动获取二级域名的接口

有些域名二级域名比较多，而且可能会变动。没办法手动添加；希望可以添加一个常见的接口（aliyun dnspod）获取二级域名信息。最好可以有过滤状态的功能，比如停止的状态的暂时不添加到域名列表里面。也可以对解析记录进行过滤，哪些是cname，txt，a记录都可以区分。
谢谢。

No files, tests, or entry points are named. First locate the existing domain-list and DNS-provider integration paths, then determine how Aliyun DNSPod authentication and record/status filters should fit the project. Done means automatic second-level-domain discovery works, excludes stopped domains when configured, and distinguishes CNAME, TXT, and A records.
