I stumbled over the same issue and found a nice solution which does not need any static ip configuration:

You can access a service via it's DNS name (as mentioned by you): servicename.namespace.svc.cluster.local

You can use that DNS name to reference it in another namespace via a local service:

kind: Service
apiVersion: v1
metadata:
  name: service-y
  namespace: namespace-a
spec:
  type: ExternalName
  externalName: service-x.namespace-b.svc.cluster.local
  ports:
  - port: 80
