FastAPI will use this return type to:

* **Validate** the returned data.

  // Multiple endpoints which use the same hostname should be considered
  // fungible (e.g. multiple A values in DNS). Must be lowercase and pass DNS
  // Label (RFC 1123) validation.
  // +optional
  optional string hostname = 3;

  // targetRef is a reference to a Kubernetes object that represents this
  // endpoint.
  // +optional

	// endpoints to distinguish endpoints from each other (e.g. in DNS names).
