# Assign a static IP address
After you disable DHCP for the RMH subnet, you need to assign a static IP address to all store computers and peripheral devices that need to access the RMH network.
1. Open **Control Panel**. To do this, click **Search**, type **Control Panel**, and press **Enter**.
2. Click **Network and Internet**.
3. Under **Network and Sharing Center**, click **View network status and tasks**.
3. Click **Change adapter settings**.

9. Select **Use the following IP address** and enter the following:
* **IP address:** Enter the IP address for the computer. Each computer connected to the network must have a unique IP address, e.g., 192.168.9.151 (POS lane 1), 192.168.9.152 (POS lane 2), 192.168.9.153 (POS lane 3).
* **Subnet mask:** Use the same subnet mask for every computer on the network.
* **Default gateway:** Enter the IP address for the router, e.g., 192.168.9.1.
10. Select **Use the following DNS server addresses** and enter the following:
* **Preferred DNS server:** Enter the IP address for the router, e.g., 192.168.9.1.

## 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.rmhpos.com/installation/nbp_topics/nbp-network-securing-and-isolating/nbp-network-assign-static-ip.md?ask=&goal=
```
`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.
