Dnsyo是一个命令行DNS检测工具，能够在多达1500个不同网络的开放DNS服务器上进行查询。在做了DNS变更的时候用来检查DNS生效或排查DNS设置的时候是非常有用的。

Dnsyo每两周更新一次DNS服务器记录数据库，在运行dnsyo命令时，下载resolver-list.yml文件并将其存储到?/.dnsyo-resolvers-list.yaml文件。

如果你知道更多的DNS服务器地址可以随意将它们添加到resolver-list-source.yml文件，也可以指定自定义的DNS地址列表文件。

Dnsyo安装

python版本需要2.6以及以上版本。

1
pip install dnsyo --upgrade
