After you add a domain name for CDN, Alibaba Cloud CDN assigns a CNAME record to the domain name. You must add a CNAME record in the system of your DNS service provider to map the domain name to the CNAME before requests can be redirected to points of presence (POPs). This topic describes how to configure a CNAME record on DNSPod.
Background information
Before you add a CNAME record, make sure that you understand the following concepts:
Prerequisites

Add a CNAME record.
Log on to the DNSPod console.
On the DNSPod page, click Add Records to add a CNAME record.

We recommend that you keep the default setting.
Click Save.
After the CNAME record takes effect, Alibaba Cloud CDN is automatically enabled for the domain name.
NoteAfter you add a CNAME record, it immediately takes effect. After you modify a CNAME record, the modifications take effect within 72 hours.
After you add a CNAME record, the system takes approximately 10 minutes to update the status of the domain name in the console. The system may prompt that you must add a CNAME record. Ignore the message.
Check whether the CNAME record takes effect.
Open the Command Prompt in Windows.
Run the ping command to ping the domain name. If the CNAME in the output is the same as the CNAME that is assigned to the domain name, CDN acceleration is enabled for the domain name.
