This topic describes how to configure a CNAME record for your accelerated domain with Alibaba Cloud Domain Name System (DNS). After a domain is added to Alibaba Cloud Dynamic Route for CDN (DCDN), Alibaba Cloud DCDN team assigns a canonical name (CNAME) to the domain. To enable the DCDN service, you must create a CNAME record to map the domain to the CNAME. In this way, requests for the domain can be sent to DCDN cache nodes.


  1. Obtain the CNAME of the accelerated domain.
    1. Log on to the Dynamic Route for CDN console..
    2. In the left-side navigation pane, click Domain Names.
    3. On the Domain Names page, find the target accelerated domain, and copy its CNAME.
  2. Check whether a new CNAME record takes effect.
    1. Open the Command Prompt in Windows.
    2. Enter ping or dig and the accelerated domain.
      If the output includes *.*kunlun*.com, both the CNAME record and the CDN service have taken effect.The new CNAME record takes effect.
