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.
