From official Kubernetes documentation, this is how External IP is described If there are external IPs that route to one or more cluster nodes, Kubernetes Services can be exposed on those externalIPs.

The most important thing here is to be sure which IP is used to reach the Kubernetes cluster. Using external IP service type, we can bind the service to the IP used to connect to the cluster.

In real life example, you might want to expose MySQL DB on 1 external IP and Kafka cluster on another external IP.
