Configuring and Changing a Floating IP Address

Scenarios

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

Constraints

After a floating IP address is changed, the domain name needs to be resolved again. This operation takes several minutes and may interrupt database connections. Therefore, you are advised to change a floating IP address during off-peak hours.

Configuring a Floating IP Address

You can use an automatically-assigned IP address when creating a DB instance.

Changing a Floating IP Address

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

Log in to the management console.
Click in the upper left corner and select a region and a project.
Click Service List. Under Database, click Relational Database Service. The RDS console is displayed.
On the Instances page, click the target DB instance name to go to the Summary page.
Under Floating IP Address, click Configure.
In the displayed dialog box, check the number of in-use IP addresses. If the in-use IP addresses are less than 254, there are unused floating IP addresses.
Select an available IP address and click OK.
An in-use IP address cannot be used as the new floating IP address of the DB instance.
