Service externalName: IP?

Below is my exact YAML file for creating the externalName Service, can you see anything wrong with it? Any ideas on what I can check next? Thanks by the way!

apiVersion: v1
kind: Service
metadata:
  name: kafka
spec:
  type: ExternalName
  externalName: 10.59.208.211
  ports:
    - name: kafka
      port: 9092
      protocol: TCP
    - name: zookeeper
      port: 2181
      protocol: TCP
