Can WAF Protect an IP Address?

A WAF instance can protect IP addresses.

Cloud Mode - CNAME Access

In this mode, only website domain names can be added to WAF for protection.

The origin server IP address configured in WAF can only be a public IP address.

To reduce the number of public IP addresses, you can use an Elastic Load Balance (ELB) load balancer to work as a proxy of backend private IP addresses. Then, you need to set the EIP (public IP address) bound to the load balancer as the origin server IP address.

Dedicated Mode/Cloud - Load Balancer Access

A dedicated or load balancing WAF instance can protect websites through either domain names or IP addresses.

The origin server IP address configured in WAF can be a public IP address or internal IP address.

For details about how to connect a domain name to WAF, see Connecting a Website to WAF.
