Internet Access

RDS supports two types of addresses: intranet address and extranet address. The intranet address is provided for users to access RDS instances internally by default. For extranet access, you can apply for an extranet address on the instance details page.

Introduction to intranet and extranet domain names

Domain name type

Description

Intranet domain name

• the intranet domain name is provided by default, and it does not need to be applied for or released and can be modified • when the database and VM are in the same region and under the same VPC, the VM can access the database via internal and external domain names without applying for an extranet domain name • intranet access is more secure, so you are recommended to access database instances via intranet.

External network domain name

• The external network domain name needs to be applied manually by the user • It is applicable to the situation that the virtual machine and the database instance are not in the same region or the network type is different, or the RDS instance is accessed through a third-party device.

Description:

There is no charge for the application of extranet domain name and the public network traffic generated by data transmission via an extranet. *Accessing via extranet domain name will reduce instance security. Please use it with caution. If necessary, please set the whitelist at the same time. *After the extranet access is disabled, the access address will change when it is enabled again.
