  # `domain_status.endpoint` hostname, and VPC instances have a `domain_status.endpoints['vpc']` hostname.
  # However VPC ElasticSearch instances create their own Network Interface and AWS will not allow you
  # to associate an Elastic IP to it. As a result VPC ElasticSearch instances are always private, even with an
  # internet gateway.
