What are records in ‘netstat’ command are when using logstash

elasticsearchlogstashnetstat

I use logstash with embedded elasticsearch. My logstash config looks like the following:

output {
  tdout { debug => true debug_format => "json"}

  elasticsearch {
    embedded => true
    cluster => "logs"
  }
}

When I issue command to see all opened ports by using

netstat -plunt

I get the following:

What means :::* in the third column are? Does it mean that embedded elasticsearch opens 9200, 9300 and 9301 ports for listening from anywhere?

If so how could I restrict elasticsearch to listen only from localhost?
