# Reserve IP addresses

***

## Reserve IP addresses using the control panel

IP addresses are reserved per [project](/platform/control-panel/projects.md).

To reserve IP addresses, select the **Reserve** tab. Here, you first choose where the IP address should be reserved. IP addresses are specific to each platform and data center. Once you have selected the platform, data center, and IP version, a list of available IP addresses will appear that you can reserve. To reserve an address, click on it to select it, and then click **Reserve x addresses** at the bottom right.

In the example below, we reserve an IPv4 address for the KVM platform in Falkenberg.

The IP addresses you reserve here can later be used for both new and existing servers within the platform and datacenter you selected. See the sections [KVM - Add or remove IP addresses](/products/compute/kvm-virtual-machines/how-tos/manage-virtual-machines.md#add-or-remove-ip-addresses) and [VMware - Manage IP address](/products/compute/vmware-virtual-machines/how-tos/manage-virtual-machines.md#manage-ip-addresses), respectively.

## Reserve IP addresses using the API

1. First, list available IP addresses with the [ip/listfree](https://github.com/GleSYS/API-docs/wiki/API-Documentation#iplistfree) endpoint of the [API](/platform/control-panel/api.md).
2. Then, reserve the IP address with the [ip/take](https://github.com/GleSYS/API-docs/wiki/API-Documentation#iptake) endpoint.
3. You can also list all of your reserved IP addresses in this project by using the [ip/listown](https://github.com/GleSYS/API-docs/wiki/API-Documentation#iplistown) endpoint.
