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.

Table 1 Domain Type

Parameter

Description

Single domain

Only one common domain name can be associated.

If you have only one domain name, select Single domain.

Multiple domains
  • Multiple domains can be added to a certificate. Multiple single domains can be set for domains. For example, you can use one multi-domain certificate to protect domains example.com, example.cn, and test.com.
  • You need to configure the domain quantity based on the number of domains you need to protect with a single multi-domain certificate.
  • The number of domain names ranges from 2 to 250. A maximum of 250 domain names can be protected with a certificate.

If you have multiple domain names, select Multiple domains. Purchase domain names of the required quantity on the purchase page.

Wildcard domain
  • Only one wildcard domain name can be associated.

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.

Table 2 Examples of wildcard-domain matching rules

Matched Domain Name

Unmatched Domain Name
  • For wildcard-domain certificates, only those associated with root domain names support the domain names. For example:
  • If the www subdomain is associated with a certificate, the certificate also protects the root domain. For example:
  • Once your digital certificate is issued, the associated domain cannot be changed.

Table 3 is given here for your reference.
