    Server Address Select the address type of the origin server and specify the address. Supported address types are as follows:
    • Origin Server IP: You can enter up to 20 IP addresses of the origin server. When multiple origin server IPs are specified, Anti-DDoS Pro uses IP hash load balancing to forward traffic back to the origin server.
    • Origin Server Domain: If you want to use Anti-DDoS Pro and WAF together for enhanced protection, you can select Origin Server Domain and enter the CNAME provided by your WAF instance.
    Origin server ports The server ports are automatically assigned based on the protocols you have selected.

After a domain is added, you are automatically directed to the Modify DNS Records page. You can click Back to go to the Websites page and view the newly added domain information.

Anti-DDoS Pro automatically associates each domain with an Anti-DDoS Pro instance IP address. You need to change the A record value of your domain to the Anti-DDoS Pro instance IP address. The incoming traffic to your site is then forwarded to your Ant-DDoS Pro Instance.
