ApsaraDB RDS supports two types of endpoints: internal endpoints and public endpoints. By default, you are provided with an internal endpoint that is used to connect to your ApsaraDB RDS for MySQL instance. If you want to connect to your RDS instance over the Internet, you must apply for a public endpoint.
For more information about how to apply for or release public endpoints for RDS instances that run other database engines, see the following topics:

Am I charged for the use of a public endpoint?
You are not charged for the inbound or outbound Internet traffic that you consume for your subscription and pay-as-you-go RDS instances. Alibaba Cloud does not impose bandwidth limits on RDS instances.
Can I change the endpoints and port numbers of my RDS instance?
You can change only the prefixes of the endpoints. You can change the port numbers of your RDS instance. For more information, see View and manage instance endpoints and ports.
Can I configure the endpoints of my RDS instance to static IP addresses?
No, you cannot configure the endpoints of your RDS instance to static IP addresses. Both primary/secondary switchovers and specification changes may cause changes to the IP addresses. We recommend that you connect to your RDS instance by using an endpoint. This allows you to minimize the impact on your workloads and eliminates the need to modify the configuration data on your application.
