Host in the [ECS](https://www.elastic.co/blog/introducing-the-elastic-common-schema) spec is an object

> <https://github.com/elastic/ecs/blob/master/generated/beats/fields.ecs.yml#L1008-L1015>

so now it's

```
host:
  name: my hostname
  ip: 10.1.10.10

```

Where "host" encapsulates "host" related data.
