    ApsaraVideo VOD:Add an accelerated domain name

    Last Updated:Jun 15, 2026

    ApsaraVideo VOD accelerates content delivery by caching origin server resources on points of presence (POPs). To enable acceleration for your website, set the site as an origin server and add an accelerated domain name.

    Prerequisites

    • You have activated ApsaraVideo VOD. If not, see Activate ApsaraVideo VOD.

    • You have a stable business server to use as an origin server.

    • You have a domain name to use for acceleration. If the acceleration region is Chinese Mainland only or Global, the domain name must have an ICP filing. If the domain name does not have an ICP filing, you can apply for one in the Alibaba Cloud ICP Filing system.

    • You have enabled the system-assigned VOD system bucket. If not, see Manage storage to enable it.

    Limitations

    • An accelerated domain name can be added only once. If you receive a Domain name already added message, check whether your domain name is already in use by other Alibaba Cloud products, such as ApsaraVideo Live, DCDN, or Video Surveillance. If you cannot resolve the issue, submit a ticket. For information about how to submit a ticket, see Contact us.

    • After you activate ApsaraVideo VOD, you can add a maximum of 20 domain names. If the average daily peak bandwidth of your domain names exceeds 50 Mbps and your services are risk-free, you can submit a ticket to request an increase in your domain name quota. For information about how to submit a ticket, see Contact us.

    • All accelerated content must be lawful and comply with business standards. For more information, see Domain name admission criteria.

    • Accelerated domain names support access over IPv6. To enable this feature, see Configure IPv6.

    Procedure

    1. Log on to the ApsaraVideo VOD console.

    2. In the left-side navigation pane, choose Configuration Management > CDN Configuration > Domain Names.

    3. Click Add Domain Name.

    4. Configure the Domain Name, Type, Port, and Acceleration Region parameters.

      Description

      Domain name

      N/A

      Note the following when you add a domain name:

      • We recommend that you use a subdomain for acceleration. The domain name can contain only lowercase English letters. Chinese domain names are not supported. For example, if your primary domain is aliyundoc.com, the accelerated domain name can be a subdomain of aliyundoc.com, such as example.aliyundoc.com.

      • ApsaraVideo VOD does not support wildcard domains, such as *.aliyundoc.com.

      Note

      The subdomain must be unique within your Alibaba Cloud account. When you add a domain name, CDN checks whether it is already in use. If the subdomain is added to another account or is already used by another Alibaba Cloud service, the system returns an error. If you cannot resolve the issue, submit a ticket. For information about how to submit a ticket, see Contact us.

      Type

      VOD Bucket

      Select this option for VOD acceleration. Then, select a VOD system bucket in the target region as the origin server from the drop-down list.

      Note

      If the drop-down list is empty, enable the system-assigned VOD system bucket in the ApsaraVideo VOD console first to generate a storage address. Otherwise, you cannot add an accelerated domain name. For more information, see Storage Management. The storage address may take some time to generate. Refresh the page later and make your selection.

      Port

      N/A

      Select the access port.

      • Port 80: CDN sends back-to-origin requests to port 80 of the origin server.

      • Port 443: CDN sends back-to-origin requests to port 443 of the origin server.

      Acceleration region

      Chinese Mainland (ICP Filing Required)

      If you select Chinese Mainland (ICP Filing Required), an ICP filing is required. For more information about how to apply for an ICP filing, see ICP filing for accelerated domain names.

      Global (ICP Filing Required)

      If you select Global (ICP Filing Required), an ICP filing is required. For more information about how to apply for an ICP filing, see ICP filing for accelerated domain names.

      Global (Excluding Chinese Mainland)

      If you select Global (Excluding Chinese Mainland), no ICP filing is required.

    5. Review the compliance statement and select I understand and agree to the above compliance warranty.

    6. Click Submit to complete the configuration.

      After you submit the configuration, a confirmation message appears. You must then add a CNAME record with your DNS provider to activate the acceleration service.

      After your accelerated domain name is reviewed and approved, it appears in the domain name list on the Domain Names page. A status of Running indicates a successful setup.

      Note

      • You can submit a ticket to request an expedited review. For information about how to submit a ticket, see Contact us.

      • The review process is faster if your origin server is an Alibaba Cloud ECS instance or an OSS bucket.

    What to do next

    After you add an accelerated domain name, Alibaba Cloud CDN assigns a CNAME to it. You must add a CNAME record at your DNS provider to point your accelerated domain name to the assigned CNAME. The CDN service takes effect only after the CNAME record is configured. For more information, see Configure a CNAME record.
