# 问题详情
cdn.jiangsu.chinatax.gov.cn
# 处理过程
结果:
```
<JSONObject>
<success>true</success>
<message>域名cdn.jiangsu.chinatax.gov.cn备案号信息:京ICP备13021685号-2</message>
</JSONObject>
```
背景:
~~`.gov.cn` 和 `.政务` 是从前往后查,其它的都是从二级开始往前查~~
```
cdn.jiangsu.chinatax.gov.cn
jiangsu.chinatax.gov.cn
chinatax.gov.cn
```
```
cdn.jiangsu.chinatax.gov.cn:不存在
jiangsu.chinatax.gov.cn:苏ICP备05002258号-2
chinatax.gov.cn:京ICP备13021685号-2
cdn.jiangsu.chinatax.gov.cnIBS 子域名查询:
{"chinatax.gov.cn":"true_京ICP备13021685号-2","jiangsu.chinatax.gov.cn":"true_苏ICP备05002258号-2"}
```
# 总结
IBS 取了 chinatax.gov.cn 的备案信息,原因:
![](../../../../attachment/images-paste/image-20250508153627395.png)
备案接口的话,.gov.cn查哪个返回哪个,其它域名会从后往前查
历史说法有误。
