Does WAF Support Wildcard Domain Names?

Does WAF Support Wildcard Domain Names?
Yes. When adding a domain name to WAF, you can configure a single domain name or a wildcard domain name based on your service requirements. The details are as follows:
- Single domain name
Configure a single domain name to be protected. For example, www.example.com
- Wildcard domain name
You can configure a wildcard domain name to let WAF protect multi-level domain names under the wildcard domain name.
- If the server IP address of each subdomain name is the same, enter a wildcard domain name to be protected. For example, if the subdomain names a.example.com, b.example.com, and c.example.com have the same server IP address, you can directly add the wildcard domain name *.example.com to WAF for protection.
- If each subdomain name points to different server IP addresses, add subdomain names as single domain names one by one.
