How can I find the value discovery.zen.ping.multicast.enabled of a cluster using API ? I tried **curl -X GET "[http://localhost:9200/\_cluster/settings?include\_defaults=true](http://localhost:9200/_cluster/settings?include_defaults=true)"** but it doesn't show the multicast enabled value. ---

Multicast networking doesn't exist in 5.x and 6.x versions, and was provided by an optional plugin in 2.x versions. See [https://github.com/elastic/elasticsearch/issues/18686#issuecomment-223078307](https://github.com/elastic/elasticsearch/issues/18686#issuecomment-223078307). ---
