# Increase Network Subnet CIDR To Add More IP addresses in Subnet

## Problem

### Can the network subnet CIDR be changed from /24 to /22 to add more IP addresses in the subnet?

## Environment

* Platform9 Managed OpenStack - All Versions
* Neutron

## Answer

* For an existing network, there is currently **NO** option in OpenStack which allows changing a network's subnet CIDR range. However, one can log in to the Clarity UI and *Edit* the existing subnet details like *Name, Gateway IP, Allocation Pools*, etc as shown below.![](https://support.platform9.com/attachments/token/NrNXtjnH2k1kR6VRoa8ubgyXD/?name=Screen+Shot+2020-02-05+at+7.25.28+PM.png)
* Also, to accommodate the extra IPs, you can create a new subnet within the same network with a */22* CIDR range by navigating through the *Network* section in the UI. $plugin\[emk72c2nbl8]

## 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://platform9.com/kb/pmo/frequently-asked-questions/increase-network-subnet-cidr-to-add-more-ip-addresses-in-subnet.md?ask=<question>&goal=<user_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.
