+Restricting IPs on Kubernetes Kapsule or Kosmos clusters enhances security by limiting access to only trusted sources, thereby reducing the risk of unauthorized access and potential attacks.
+This control ensures that only specific IP addresses or networks can interact with your clusters, providing an additional layer of protection.
+The default entry `0.0.0.0/0` enables any host to establish a connection.

+## How to add an IP address
+
+1. Click **Kubernetes** in the **Containers** section of the [Scaleway console](https://console.scaleway.com). The Kubernetes Kapsule dashboard appears.
+2. Select the cluster you wish to configure. The **Cluster information** page opens.
+3. Click the **Allowed IPs** tab to view your current list.
+4. Click **Add allowed IP**. Enter the IP address or IP block in CIDR format (e.g. `198.51.100.135/32` for a single IP, `198.51.100.0/24` for an IP block).
+    <Message type="note">
+      To restore default settings and allow connections from all IPs, add `0.0.0.0/0` to the list.
+    </Message>
+
+<Message type="important">
+    For **Kosmos** multi-cloud clusters, allow connections from all Scaleway IP subnets to ensure proper functionality. Access from these IPs cannot be restricted. Refer to our [peering information](https://www.scaleway.com/en/peering/) for details on all Scaleway IP prefixes.
