Does WAF support connecting wildcard domain names?

Yes. You can connect a wildcard domain name in the WAF Console.

Note：

• If a wildcard domain name, such as *.test.com, is already connected to Tencent Cloud, then any of its sub-domain names cannot be connected to another account.
• If the wildcard domain name *.test.com is already connected to your account, then wildcard domain names in formats such as *.a.test.com cannot be connected to this account.
• If you add both a wildcard and a precise domain name (e.g. *.test.com and a.test.com), WAF first uses the protection policies configured for the precise domain name.

How long does it take to update the DNS resolution (protection) status of my domain name?
