因為 n88.ns.yunjiasu.com. 回答 NS 是 cloudflare.

dig ns kmlvip.com @n88.ns.yunjiasu.com.

@hgc81538
请问用哪种命令或方法可以直观看到 n88.ns.yunjiasu.com 回答的 NS 是 cloudflare.
我使用了你给的命令行，没有请求回应
```base

@sunweiqiang8 不要带 @ 带 @ 是给递归 DNS 服务器去查询

C:\Users\Showfom>dig ns kmlvip.com n88.ns.yunjiasu.com

汗。修改 ns 的纪录光改本域的数据是不行的。需要在你注册域名的那里修改！我刚干过这事情，具体过程： http://ming.theyan.gs/2017/08/How-to-migrate-your-own-NS-servers/
好大的坑这里

@hawhaw LZ 使用的第三方权威 NS 服务 非自己域名的子域名作为权威 NS 所以跟你这个情况不一样的
