No, if you don't then it uses the default as mentioned at [Discovery and cluster formation settings | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-settings.html);

> The default value for `discovery.seed_hosts` is `["127.0.0.1", "[::1]"]`
