Configure an IP Access List

For each TiDB Cloud Dedicated 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 Dedicated cluster.

Add an IP address

To add an IP address to the IP access list for your TiDB Cloud Dedicated cluster, take the following steps:

1. Navigate to the My TiDB page, and then click the name of your target TiDB Cloud Dedicated cluster to go to its overview page.

   Tip

   If you are in multiple organizations, use the combo box in the upper-left corner to switch to your target organization first.

2. In the left navigation pane, click Settings > Networking.

3. On the Networking page, click Add IP Address.

4. In the Add IP Address dialog, add IP addresses with an optional description. For each TiDB Cloud Dedicated cluster, you can add up to 100 IP addresses.

   • To add a custom IP address, click the + icon, enter the IP address in CIDR notation (for example, 192.168.1.1/32), and add a description.
   • To add the current IP address of your computer, click Add Current IP.
   • To allow any IP address to access your cluster, click Allow access from anywhere. This adds the 0.0.0.0/0 CIDR entry. This is highly risky and NOT recommended for production environments.

5. Click Save.
