Configuring and Changing a Floating IP Address

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

To use floating IP addresses, you need to contact customer service to apply for the required permissions.

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

After a DB instance is created, you can change its floating IP address.

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 Instance Management page, click the target DB instance.
In the Connection Information area on the Basic Information page, click Change in the Floating IP Address field.
In the displayed dialog box, enter a new floating IP address and click OK.
- After the 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 the floating IP address during off-peak hours.
- In the in-use IP address list, the IP addresses whose statuses are Idle are occupied and cannot be used.
