  1. Complete ICP filing: According to the laws of China and the requirements of the Ministry of Industry and Information Technology (MIIT), you must complete an ICP filing for domain names that are resolved to websites and apps whose servers are located in the Chinese mainland before the websites and apps can provide services. If you have completed an ICP filing for the domain name, you can proceed to the next step.

  2. Activate Alibaba Cloud CDN: Log on to the Alibaba Cloud console and activate Alibaba Cloud CDN.

  3. Add a domain name: After you add a domain name in the Alibaba Cloud CDN console, the system pushes the configuration of the domain name to all points of presence (POPs). The first time you add a domain name to Alibaba Cloud CDN, you need to verify the ownership of a domain name by using a DNS record of the domain name. Once the domain passes the verification, its subdomains do not require separate ownership verification.

  4. (Optional) Configure system-recommended features: After you add a domain name to Alibaba Cloud CDN, we recommend that you configure features, such as cache expiration, bandwidth cap, and HTML optimization, for the domain name. This improves the cache hit ratio, security, and access performance of Alibaba Cloud CDN.

  5. (Optional) Test whether a domain name is accessible: After you add a domain name to Alibaba Cloud CDN, we recommend that you perform a local test on the domain name to verify that the domain name is accessible and then map the DNS record of the domain name to the CNAME. This ensures that DNS updates do not affect the services.

  6. Add a CNAME record for a domain name: After you add a domain name, Alibaba Cloud CDN assigns a CNAME to the domain name. You need to add a CNAME record in the system of your DNS service provider to map the domain name to the CNAME before acceleration can take effect.
