Configuring CNAME Records
After a domain name is added, the system automatically assigns a CNAME value to the domain name. You need to add the CNAME record to your domain's DNS records. Acceleration is enabled once the configuration takes effect.
Notes
- If your domain name is registered on the HUAWEI CLOUD Domain Registration Service, configure the CNAME record by referring to the following procedure.
- If your domain name is registered with a third-party domain registrar, create a public zone and add the domain name to the Domain Name Service (DNS) service. Then, follow the procedure to configure the CNAME record. You can also configure the CNAME record at your own DNS provider by following the configuration guide provided by your DNS provider.
- Configure CNAME records for the ingest domain name and streaming domain name separately.
Procedure
The following uses a streaming domain name as an example. The procedure for configuring the CNAME record for an ingest domain name is the same.
- Obtain the CNAME value.
- Log in to the Live console. In the navigation pane, choose Domains.
- Click Settings in the row containing the target streaming domain name. The basic information page is displayed.
Obtain the CNAME value of the streaming domain name.
Figure 1 Streaming Info
Use play-test.example.com as an example. Its CNAME value is play-test.example.com.c.cdnhwc3.com.
- Log in to the DNS console.
- In the navigation pane, choose DNS Resolution > Public Zones. The public zone list is displayed.
- Click the target domain name in the Name column.
Use the domain name example.com as an example. Locate the row containing example.com.

- In the upper right corner of the page, click Add Record Set.Figure 3 Adding a record set
Configure the parameters as instructed. Table 1 describes the parameters.Table 1 Parameter description Parameter
Description
Example Value
Name
Enter the level-2 domain name. You do not need to enter the suffix.
For example, if the streaming domain name is play-test.example.com, enter play-test.
Type
Type of the record set, which should be CNAME-Canonical name here
CNAME-Map one domain to another
Alias
Whether to associate the record set with a cloud resource name
- Yes: Associate the record set with a cloud resource. For details, see Record Set.
- No: Do not associate the record set with a cloud resource.
No
Line
Resolution line. The DNS server will return the IP address of the specified line based on the source of visitors. For details, see Resolution Line.
The default value is Default.
This parameter is supported only for public domain names.
Default
TTL (s)
Cache duration of the record set (unit: s)
The smaller the value is, the quicker the record takes effective.
The default value is 5 min. If there are no special requirements, retain the default value.
Value
Domain name to be pointed to, that is, the CNAME obtained in step 1
For example, if the streaming domain name is play-test.example.com, enter play-test.example.com.c.cdnhwc3.com.
Weight
(Optional) Weight of a record set. When multiple record sets of the same name and line are created in a zone, the one with a larger weight takes effect in priority. The default value is 1.
This parameter is supported only for public domain names.
The value ranges from 0 to 100.
1
Tags
(Optional) This item is displayed when you switch on Other Settings. This parameter indicates the identifier of a resource. Each tag contains a key and a value. You can add a maximum of 10 tags to a record set.

- Click OK.
The record set you added is displayed in the list. If the status of the record set is Normal, the record set has been added.
- Perform step 1 to step 6 to configure the CNAME for the ingest domain name.
Verifying that the CNAME Has Taken Effect
Open the command line interface that comes with Windows and run the following command:
nslookup -qt=cname Acceleration domain name
