Unbinding an EIP

Scenarios

The Elastic IP (EIP) service enables your RDS instances to communicate with the Internet using static public IP addresses and scalable bandwidths. But this increases the risk of network-wide attacks on your instances. Using an EIP leaves you open to DoS or DDoS attacks.

As an internal component, the database can be accessed using an internal IP address. Therefore, you are advised to unbind the EIP from the database.

Prerequisites

An EIP has been bound to your DB instance. For details, see Binding an EIP.

Unbinding an EIP

1. Log in to the management console.
2. Click in the upper left corner of the page and choose Databases > Relational Database Service.
3. On the Instances page, click the DB instance with an EIP bound to go to the Overview page.
4. In the navigation pane on the left, choose Connectivity & Security. In the Connection Information area, click Unbind next to the EIP field. In the displayed dialog box, click OK.

   Alternatively, in the Connection Topology area, click Public Connection and then Unbind in the connection topology. In the displayed dialog box, click OK.

5. On the Connectivity & Security page, check the results.

   You can also view the progress and result of unbinding an EIP from a DB instance on the Task Center page.

   To bind an EIP to the DB instance again, see Binding an EIP.
