Unbinding an EIP

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.

Unbinding an EIP

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service.
  4. On the Instances page, click the DB instance that has an EIP bound to go to the Basic Information page.
  5. In the navigation pane on the left, choose Connectivity & Security. In the Connection Information area on the Public Connection page, click Unbind next to the EIP field. In the displayed dialog box, click Yes.
  6. On the Connectivity & Security page, check the result.

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