Configure Alibaba Cloud CDN in accelerated regions outside mainland China in the CDN console

Step 1: Activate Alibaba Cloud CDN

1. Log on to the Alibaba Cloud CDN console to activate Alibaba Cloud CDN.
2. On the Alibaba Cloud CDN page, select a Billing Method.
   For more information about the pricing of Alibaba Cloud CDN, see Billing rules.
3. Select I agree with Alibaba Cloud CDN Agreement of Service and click Enable Now.

Step 2: Add the domain name to be accelerated

1. In the left-side navigation pane, click Domain Names.
2. On the Domain Names page, click Add Domain Name.
3. Set the following parameters: Domain Name to Accelerate, Resource Groups, Business Type, Port, and Region.
   Note To accelerate content delivery in Hong Kong, Macao, Taiwan, and other regions outside mainland China, select Global or Global (Excluding Mainland China). If you select Global as the accelerated region, the accelerated domain name must obtain an Internet Content Provider (ICP) number.We recommend that you apply for an ICP number through Alibaba Cloud ICP Filing System.

   Parameter	Value	Description
   Domain Name to Accelerate	-	Enter the domain name that you want to add to Alibaba Cloud CDN, for example, ch.aliyun.com. Note that: You can use a subdomain name or a wildcard domain name as the accelerated domain name, for example, cdntest.example.com. You cannot add a duplicate domain name to Alibaba Cloud CDN. If a DomainAlreadyExist error occurs, submit a ticket. You can add at most 50 domain names to Alibaba Cloud CDN under each Alibaba Cloud account. To add more domain names, submit a ticket. Content that is delivered from your domain name must comply with the limits of Alibaba Cloud CDN and the relevant regulations. For more information, see Limits.
   Business Type	Image and Small File	If you want to accelerate the delivery of small-sized static content on your website, we recommend that you select Image and Small File from the Business Type drop-down list. Examples of small-sized static content include small-sized files, images, and style sheets.
   	Delivery of large files	If you want to accelerate the delivery of static files larger than 20 MB, we recommend that you select Large File Download from the Business Type drop-down list. Examples of large-sized static files include game installation packages, app update packages, mobile read-only memory (ROM) upgrade packages, and app packages.
   	VOD	If you want to accelerate the delivery of on-demand video or audio content, we recommend that you select VOD from the Business Type drop-down list.
   Origin Info	IP	You can enter the public IP addresses of one or more servers. IP addresses of Alibaba Cloud Elastic Compute Service (ECS) instances do not need to be reviewed.
   	Site Domain	You can enter the domain names of one or more origin servers. Note The domain name of the origin server that you specified cannot be the same as the accelerated domain name. Otherwise, a DNS resolution loop occurs and requests cannot be redirected to the origin server correctly. For example, if the domain name of your origin server is img.yourdomain.com, you can set the accelerated domain name to cdn.yourdomain.com.
   	OSS Domain	You can enter the public endpoint of an Alibaba Cloud Object Storage Service (OSS) bucket, for example, xxx.oss-cn-hangzhou.aliyuncs.com. To view the public endpoint of an OSS bucket, go to the OSS console. You can also select the endpoint of an OSS bucket under the current Alibaba Cloud account from the Domain Name drop-down list.
   	Function Compute Domain	If you select this value, you must set the Region and Domain Name parameters.
   Port	-	Select a port based on your business requirements. Port 80 Data is transmitted over HTTP. Port 443 Data is transmitted over HTTPS.
   Region	Global (Excluding Mainland China)	If you select Global (Excluding Mainland China), you do not need to obtain an ICP number for the domain name.
   	Global	If you select Global, you must obtain an ICP number for the domain name. For more information, see Apply for an Internet Content Provider (ICP) number for an accelerated domain name.
   	Mainland China Only	If you select Mainland China Only, you must obtain an ICP number for the domain name. For more information, see Apply for an Internet Content Provider (ICP) number for an accelerated domain name.

4. Click Next.

Step 3: Configure a CNAME record

After you add a domain name to Alibaba Cloud CDN, Alibaba Cloud CDN verifies the ownership of the domain name. After the domain name passes the ownership verification, Alibaba Cloud CDN assigns a Canonical Name (CNAME) to the domain name. To enable CDN acceleration for the domain name, you must add a CNAME record to map the domain name to the CNAME. This way, requests sent to the domain name can be redirected to CDN nodes. The following example demonstrates how to add a CANME record for the domain name. Alibaba Cloud DNS (previously known as HiChina) is used in the example.

1. Obtain the CNAME assigned to the domain name.
   1. In the left-side navigation pane, click Domain Names.
   2. On the Domain Names page, copy the CNAME of the accelerated domain name.
2. Add a CNAME record.
   1. Log on to the Alibaba Cloud DNS console.
   2. On the Manage DNS page, click the Domains tab, select the domain name that you want to manage, and then click Configure in the Actions column.
   3. Click Add Record and add a CNAME record.
   4. Click OK.

      The CNAME record is added. CDN acceleration is automatically enabled for the domain name immediately after the CNAME record takes effect. After you add a CNAME record, it immediately takes effect. After you modify a CNAME record, the modifications take effect within 72 hours.

3. Check whether the CNAME record has taken effect.
   1. Open the Command Prompt in Windows.
   2. Enter ping or dig and the accelerated domain name into the Command Prompt.
      If the output includes *.*kunlun*.com, both the CNAME record and CDN acceleration have taken effect.
