If you have integrated HTTPDNS through SDK integration, DoT/DoH, and JSON API, you can view domain name resolution information through resolution logs.
How to use
Log on to the Alibaba Cloud DNS-Logs page.
On the Logs page, select HTTPDNS under the Query Logs tab.

Table header parameters
Responded At: The time when the domain name query was answered.
Resolution Delay: The overall delay from when HTTPDNS receives the domain name query request to when it returns the query result.
Source IP Address: The IP address that initiates the domain name query request, typically the terminal IP address.
IP Address Carried in ECS: Refers to the client request carrying the edns-client-subnet (ECS) field, which places the client source IP in the ECS protocol extension so that the authoritative DNS makes more precise scheduling.
Query Zone Name: The target domain name queried in this DNS request.
Query Record Types: Resolution types such as A, AAAA, CNAME, TXT, MX, etc.
Access Protocol: The protocol used for the domain name query request, commonly DoT, DoH, HTTP, and HTTPS.
Resolution Result: The resolution result returned for this domain name query request.
Response Status: Generally includes the following statuses:
Status | Description |
NOERROR | Successful response, indicating successful resolution. |
NXDOMAIN (Non-Existent Domain) | The queried domain name does not exist. |
SERVFAIL (Server Failure) | The query cannot be processed because of problems with the target DNS server. |
REFUSED | The DNS server refuses to perform the specified operation due to policy reasons. For example, the current account has an overdue payment, AK/SK errors, etc. |
DNS Server IP Address: The IP address of the DNS server that responded to this DNS query request.
