Viewing and Changing a Floating IP Address


You can change floating IP addresses after migrating on-premises databases or other cloud databases to RDS.


Changing the floating IP address will interrupt the database connection. You are advised to change a floating IP address during off-peak hours.


When you buy a DB instance, select a VPC and subnet on the Buy DB Instance page. Then, a floating IP address will be automatically assigned to your instance.

You can change the floating IP address of an existing DB instance.

  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 name.
  4. In the Connection Information area on the Basic Information page, click Change next to the Floating IP Address field.

  5. Enter an available IP address and click Yes.

    An in-use IP address cannot be used as the new floating IP address of the DB instance.
