Our network team says there an IP address in a subnet is being claimed and released seemingly at random. They are wondering if Kubernetes could be doing it.
I know that Pods, Services and Nodes can have IP addresses in Kubernetes. I have checked all of those and none of them are doing it.
Is there anything else that can have an IP address in Kubernetes?
I am running an on premises Kuberentes cluster using Istio with node port services. Is there anything else that could be attempting to get an IP address?
