After you add a domain name in the ApsaraVideo VOD console, ApsaraVideo VOD assigns a canonical name (CNAME) to the domain name. You must add a CNAME record to map the domain name to the CNAME. This way, ApsaraVideo VOD forwards requests destined for the domain name to CDN nodes. This topic describes how to configure a CNAME record on Xinnet.
- Obtain the CNAME assigned to the domain name for CDN.
- Log on to the ApsaraVideo VOD console.
- In the left-side navigation pane, choose .
- On the Domain Names page, move the pointer over the View icon, and copy the CNAME
of the domain name for CDN.
- Add a CNAME record.
- Log on to the DNS console of Xinnet.
- Find the domain name that you want to manage, navigate to the Manage DNS page, and then click Add Record.
- Set the required parameters.Note Each domain name for CDN has one CNAME. The CNAME of a primary domain name cannot be used by a second-level domain name. If you need to accelerate a second-level domain name, you must add the domain name to Alibaba Cloud CDN and resolve it to the corresponding CNAME. You can also add a wildcard domain name to Alibaba Cloud CDN because the CNAME of a wildcard domain name can be used by a second-level domain name.
