# 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.cn，IBS 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：
|
||
|
||
|
||
|
||
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。
