这两年随着dns-over-https(DoH)普及，DNS 污染的问题得到了很大程度的改善，但是相比以前可以直接使用nslookup 直接查询域名解析结果，DoH 可以直接通过访问网页的方式返回解析结果。

以阿里云的DoH为例：

DoH JSON API - 阿里云公共DNS - 阿里云


 

#http://dns.alidns.com/resolve?name=解析域名.&type=1 

http://dns.alidns.com/resolve?name=www.taobao.com.&type=1 

返回json结果：

{"Status":0,"TC":false,"RD":true,"RA":true,"AD":false,"CD":false,"Question":{"name":"www.taobao.com.","type":1},"Answer":[{"name":"www.taobao.com.","TTL":42,"type":5,"data":"www.taobao.com.danuoyi.tbcache.com."},{"name":"www.taobao.com.danuoyi.tbcache.com.","TTL":42,"type":1,"data":"39.175.110.233"},{"name":"www.taobao.com.danuoyi.tbcache.com.","TTL":42,"type":1,"data":"39.175.110.232"},{"name":"www.taobao.com.danuoyi.tbcache.com.","TTL":42,"type":1,"data":"111.3.78.233"},{"name":"www.taobao.com.danuoyi.tbcache.com.","TTL":42,"type":1,"data":"111.3.78.232"}]}
