How Does WAF Calculate Domain Name Quota Usage?

The number of domain names protected by WAF is calculated as follows:

• The number of domain names is the total number of top-level domain names (for example, example.com), single domain names/second-level domains (for example, www.example.com), and wildcard domain names (for example, *.example.com).
• Each combination of a domain name and a port is counted towards the domain name quota of the WAF edition you are using. For example, www.example.com:8080 and www.example.com:8081 use two domain names of the quota.
• You can upload as many certificates in WAF as the number of domain names that can be protected by your WAF instances in the same account. For example, if you purchase a standard edition WAF instance, which can protect 10 domain names, a dedicated WAF instance, which can protect 2,000 domain names, and a domain name expansion package (20 domain names), your WAF instances can protect 2,030 domain names total (2,000 + 20 +10). In this case, you can upload 2,030 certificates.
