How does it work?
This criterion lets you match based on the version of the IP protocol the requesting client is using.
From the drop-down list, select the IP version of the client request, either IPV4 or IPV6.
Additional options
X-Forwarded-For IP: You can select whether to use the client IP address from the connecting IP address or the X-Forwarded-For header value.
When a client connects to the edge platform using an HTTP proxy or a load balancer, the X-Forwarded-For HTTP header identifies the originating IP address of that client.
