# Assign a static IP address
This topic describes how to assign a static IP address to all store computers and peripheral devices that need to access the RMH network.
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**.
3. Double-click the computer's physical network connection (Ethernet adapter).
3. Click **Properties**.
4. On the **Networking** tab, ensure that **Internet Protocol Version 4 (TCP/IPv4)** is selected.
8. Click **Properties**.
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.
* **Alternate DNS server:** Enter the IP address of a public DNS server, e.g., 8.8.8.8 for Google.
11. Click **OK**.
12. Click **OK**.
13. Click **Close**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
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 what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
