+
+# Configure an IP Access List
+
+For each TiDB Cloud Premium cluster in TiDB Cloud, you can configure an IP access list to filter internet traffic trying to access the cluster, which works similarly to a firewall access control list. After the configuration, only the clients and applications whose IP addresses are in the IP access list can connect to your TiDB Cloud Premium cluster.
+
+> **Note:**
+>
+> This document applies to [**TiDB Cloud Premium**](/tidb-cloud/select-cluster-tier.md#tidb-cloud-premium). For instructions on configuring an IP access list for **{{{ .starter }}}** or **{{{ .essential }}}**, see [Configure {{{ .starter }}} or Essential Firewall Rules for Public Endpoints](/tidb-cloud/configure-serverless-firewall-rules-for-public-endpoints.md).
+
+To configure an IP access list for your TiDB Cloud Premium cluster, take the following steps:
+
+1. Navigate to the [**TiDBs**](https://tidbcloud.com/tidbs) page, and then click the name of your target cluster to go to its overview page.
+
+    > **Tip:**
+    >
+    > You can use the combo box in the upper-left corner to switch between organizations.
+
+2. In the left navigation pane, click **Settings** > **Networking**.
+3. On the **Networking** page, click **Enable** on the **Public Endpoint** to enable connections to the public endpoint of this cluster. Then click **Edit IP Address**.
+4. In the displayed dialog, choose one of the following options:
+
+    - **Allow access from anywhere**: allows all IP addresses to access TiDB Cloud. This option exposes your cluster to the internet completely and is highly risky.
+    - **Use IP addresses** (recommended): you can add a list of IPs and CIDR addresses that are allowed to access TiDB Cloud via a SQL client.
+
+5. If you choose **Use IP addresses**, add IP addresses or CIDR ranges with an optional description. For each TiDB Cloud Premium cluster, you can add up to 100 IP addresses.
+6. Click **Confirm** to save your changes.

+# Connect to TiDB Cloud Premium via Public Connection
+
+This document describes how to connect to your TiDB Cloud Premium cluster via public connection. The public connection exposes a public endpoint with traffic filters, so you can connect to your TiDB Cloud Premium cluster via a SQL client from your laptop.
+
+> **Tip:**
+>
+> - To learn how to connect to a {{{ .starter }}} or {{{ .essential }}} cluster via public connection, see [Connect to {{{ .starter }}} or Essential via Public Endpoint](/tidb-cloud/connect-via-standard-connection-serverless.md).
+> - To learn how to connect to a TiDB Cloud Dedicated cluster via public endpoint, see [Connect to TiDB Cloud Dedicated via Public Connection](/tidb-cloud/connect-via-standard-connection.md).
+
+## Prerequisite: Configure IP access list
+
+For public connections, TiDB Cloud Premium only allows client connections from addresses in the IP access list. If you have not configured the IP access list, follow the steps in [Configure an IP Access List](/tidb-cloud/configure-ip-access-list-premium.md) to configure it before your first connection.
+
+## Connect to the cluster
+
+To connect to a TiDB Cloud Premium cluster via public connection, take the following steps:
+
+1. Open the overview page of the target cluster.
+
+    1. Log in to the [TiDB Cloud console](https://tidbcloud.com/) and navigate to the [**TiDBs**](https://tidbcloud.com/tidbs) page of your project.

+        > **Tip:**
+        >
+        > You can use the combo box in the upper-left corner to switch between organizations.
+
+    2. Click the name of your target cluster to go to its overview page.
+
+2. Click **Connect** in the upper-right corner. A connection dialog is displayed.
+
+3. In the connection dialog, select **Public** from the **Connection Type** drop-down list.
+
+    If you have not configured the IP access list, click **Configure IP Access List** or follow the steps in [Configure an IP Access List](/tidb-cloud/configure-ip-access-list-premium.md) to configure it before your first connection.
+
+4. Click **CA cert** to download CA cert for TLS connection to TiDB clusters. The CA cert supports TLS 1.2 version by default.
+
+5. Choose your preferred connection method, and then refer to the connection string and sample code on the tab to connect to your cluster.
+
+## What's next
+
+After you have successfully connected to your TiDB cluster, you can [explore SQL statements with TiDB](/basic-sql-operations.md).

+# Delete a TiDB Cluster
+
+This document describes how to delete a TiDB cluster on TiDB Cloud.
+
+You can delete a cluster at any time by performing the following steps:
+
+1. Navigate to the [**TiDBs**](https://tidbcloud.com/tidbs) page of your project.
+2. In the row of your target cluster to be deleted, click **...**.
+
+    > **Tip:**
+    >
+    > Alternatively, you can also click the name of the target cluster to go to its overview page, and then click **...** in the upper-right corner.
+
+3. Click **Delete** in the drop-down menu.
+4. In the cluster deleting window, confirm the deletion:
+
+    Enter `<organization name>/<cluster name>` to ensure the cluster is deleted correctly.
+
+    If you want to restore the cluster sometime in the future, make sure that you have a backup of the cluster. Otherwise, you cannot restore it anymore. For more information about how to back up TiDB Cloud Dedicated clusters, see [Back Up and Restore TiDB Cloud Dedicated Data](/tidb-cloud/backup-and-restore-premium.md).
+
+    > **Note:**
+    >
+    > [{{{ .starter }}}](/tidb-cloud/select-cluster-tier.md#tidb-cloud-serverless) and [{{{ .essential }}}](/tidb-cloud/select-cluster-tier.md#essential) clusters do not support restoring data after the deletion. If you want to delete a {{{ .starter }}} or {{{ .essential }}} cluster and restore its data in the future, see [Export Data from {{{ .starter }}} or Essential](/tidb-cloud/serverless-export.md) to export your data as a backup.
+
+5. Click **I understand, delete it**.
+
+    Once a backed up TiDB Cloud Dedicated cluster is deleted, the existing backup files of the cluster are moved to the recycle bin.
+
+    - Automatic backups will expire and be automatically deleted once the retention period ends. The default retention period is 7 days if you don't modify it.
+    - Manual backups will be kept in the Recycle Bin until manually deleted.
+
+    > **Note:**
+    >
+    > Please be aware that backups will continue to incur charges until deleted.
+
+    If you want to restore a TiDB Cloud Premium cluster from recycle bin, see [Restore a deleted cluster](/tidb-cloud/backup-and-restore-premium.md#restore-a-deleted-cluster).
