Need to create a elasticsearch cluster where the environment is dual stack.

From the document came to know that we can configure `network.host: 0.0.0.0` to make it bind on all the available interfaces, in this case it can listen on both IPV4 and IPV6 interface.

Is there a possibility that we can configure `network.publish_host` to include both IPv4 and IPV6. So that other nodes can reach by using any of the IPV4/V6 address if there is any issue in reaching via either of them.

What is the best way to configure ES cluster in dual stack environment.

Thanks,  
Mahudees

No. From [the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html#advanced-network-settings) (emphasis mine):

> You can specify a list of addresses for `network.host` and `network.publish_host` . You can also specify a single hostname which resolves to multiple addresses. If you do this then **Elasticsearch chooses one of the addresses for its publish address**. This choice uses heuristics based on IPv4/IPv6 stack preference and reachability and may change when the node restarts. **You must make sure that each node is accessible at all possible publish addresses**.

If a node is unreachable at its publish address then it will leave the cluster. This might happen occasionally, but as long as the cluster is [designed for resilience](https://www.elastic.co/guide/en/elasticsearch/reference/current/high-availability-cluster-design.html) then service will not be interrupted.

Thanks @DavidTurner, for the clarification.
