Overview
If you select a fine-grained line in the Domain Name System (DNS) record of a domain name for intelligent DNS resolution, you can use the DNS traffic analysis feature to check whether a DNS request for the domain name matches the selected line. This way, you can determine whether a DNS request from the resolution line is sent and responded to.
This capability only applies to domain names for which the DNS traffic analysis feature is enabled, regardless of whether the domain names are bound to free or paid Alibaba Cloud DNS instances. To view the information about matched DNS lines, enable the DNS traffic analysis feature for desired domain names. For more information, see Enable or disable the DNS traffic analysis feature for domain names.
Procedure
Log on to the Alibaba Cloud DNS console.
On the Authoritative Domain Names tab of the Authoritative DNS Resolution page, find the desired domain name and click the line chart icon in the DNS Traffic Analysis column.
On the DNS Traffic Analysis tab, click Analysis of Matched DNS Lines.
Query data based on specific criteria
Query data by time range
You can query data in a custom time range within the last 90 days. Data collected within the custom time range is aggregated and displayed. The DNS resolution lines that are matched with DNS requests are ranked based on the number of DNS requests in ascending or descending order.
Query data by domain name
By default, the number of DNS requests for all subdomain names that match DNS resolution lines is displayed. You can filter data to view the number of DNS requests for a specific subdomain name that match DNS resolution lines.
Query data by line
By default, all matched DNS resolution lines are displayed. You can filter data to view a specific line.
