Can WAF Protect an IP Address?

A WAF instance can protect IP addresses.

Cloud Mode

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

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.
