# Command: DHCP

Format: `DHCP ON` or `DHCP OFF`

Sets the device flag for persistent DHCP requests. The device will request a DHCP address on boot (if the static address is 0.0.0.0). If none is supplied, the device will use the fallback address, but will continue requesting a DHCP address. If and when a DHCP address is provided, the device will reboot and ask again for a DHCP address.

This mode is provided for systems that include a DHCP server that boots more slowly than the device.

{% hint style="info" %}
Most system do not include a DHCP server.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ceruleansonar.com/c/ethernet-rov-locator/communicating-with-the-rovl/messages-from-host-to-rovl/valid-commands-from-host-to-rovl-ethernet-only/command-dhcp.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
