Does SPLUNK require K8S clusters to have unique pod and service CIDR's

[soxprox]

I am setting up a number of Kubernetes clusters in my organisation. We are using SPLUNK for monitoring. I have been told that I will need to ask the network team to reserve 2 CDIR range's for pods and services on each cluster because SPLUNK requires it.

Can anyone clarify if SPLUNK does require every kubernetes cluster on the network to have a unique CIDR range for pods and services?
