# Geo fields
Geo fields can carry data about a specific location related to an event.
This geolocation information can be derived from techniques such as Geo IP, or be user-supplied.

## Field reuse

The `geo` fields are expected to be nested at:
- `client.geo`
- `destination.geo`
- `host.geo`
- `observer.geo`
- `server.geo`
- `source.geo`
- `threat.enrichments.indicator.geo`
- `threat.indicator.geo`

Note also that the `geo` fields are not expected to be used directly at the root of the events.
