How do I configure CNAME?
You cannot access the CNAME domain name directly. You need to complete the CNAME configuration at your domain name service provider. WAF will protect your domain name after the configuration takes effect. For more information, see CNAME Configuration.
If you have completed CNAME configuration, after you connect your domain name to WAF, the system will automatically assign a CNAME domain name suffixed with 
.qcloudxxx.com (for example, .qlcoudcjpj.com and qcloudwzgj.com), which is displayed in Instance information on the domain name list page in the WAF console.
