Yes. You can add a wildcard domain name in the WAF console.
- When a wildcard domain is added to WAF, other Tencent Cloud users can still add subdomain names that match the wildcard domain name to WAF.
- If you add both a wildcard and a precise domain name (e.g.
a.test.com), policies of the precise domain name prevail.
After you add the CNAME record at your DNS provider, status of the domain name on WAF is updated in 10 to 20 minutes. If you don’t see the update in 30 minutes, please check the CNAME configuration or submit a ticket.
The intermediate IP is subject to be changed by WAF. You will be notified by an SMS message, an email, or a message in Message Center if your intermediate IP address changes. You can check the effective intermediate IP o the Domain Name List page of the WAF console.

If the domain name points to a real server in the Chinese mainland, an ICP filling number is required.
If the instance to which you add the domain name is a SaaS WAF instance, you also need to add a CNAME record at the DNS service provider of the domain name. Set the record value to the CNAME allocated by WAF.
WAF performs origin-pull based on domain name or IP. You can choose which option to configure as you need. For more information, see Add a Domain Name.
Yes. You can check the CNAME in the Domain Name List page in the WAF console.
