What Are the Differences Between a Single-Domain Name, Multi-Domain Name, and Wildcard-Domain Name in SCM?
In SCM, options for Domain Type can be Single domain, Multiple domains, or Wildcard.
Parameter |
Description |
---|---|
Single domain |
Only one common domain name can be associated. If you have only one domain name, select Single domain. |
Multiple domains |
If you have multiple domain names, select Multiple domains. Purchase domain names of the required quantity on the purchase page. |
Wildcard domain |
If all of your domain names are at the same level, select Wildcard. |
Before you purchase a wildcard-domain certificate, pay attention to the domain name matching rules. Table 2 are some examples.

*.huaweicloud.com |
test.huaweicloud.com, yun.huaweicloud.com, example.huaweicloud.com, and other domain names |
abc.test.huaweicloud.com, yun.test.huaweicloud.com, example.test.huaweicloud.com, and other domain names |
*.test.huaweicloud.com |
abc.test.huaweicloud.com, yun.test.huaweicloud.com, example.test.huaweicloud.com, and other domain names |
abc.huaweicloud.com, yun.huaweicloud.com, example.huaweicloud.com, and other domain names |

- For wildcard-domain certificates, only those associated with root domain names support the domain names. For example:
- A certificate associated with the wildcard domain *.huaweicloud.com (a root domain) protects huaweicloud.com and other domain names of the same level. No additional certificate needs to be purchased for this.
- A certificate associated with the wildcard domain *.p1.huaweicloud.com (not a root domain) will not protect p1.huaweicloud.com (a different level domain). It can only protect domain names of the same level. To protect p1.huaweicloud.com, you would need to purchase a new certificate.
- If the www subdomain is associated with a certificate, the certificate also protects the root domain. For example:
A certificate purchased for domain www.huaweicloud.com can also protect huaweicloud.com. There is no need to purchase another certificate.
- Once your digital certificate is issued, the associated domain cannot be changed.
Table 3 is given here for your reference.
