To access an Object Storage Service (OSS) bucket over the internal network from an Elastic Compute Service (ECS) instance in another region or a device in an on-premises data center, you can use Cloud Enterprise Network (CEN), Express Connect, leased lines, or virtual private networks (VPNs) to connect to the internal network of the region where the OSS bucket is located. Then, you can configure a route that directs to the virtual IP address (VIP) ranges of the internal network. This topic describes the VIP ranges of the OSS internal network in each region.

Warning
  • OSS divides the VIP ranges of the internal network in each region into fixed address ranges. When you configure routes based on regions, you must configure complete routes based on the VIP ranges described in the following table.
  • When you access OSS over the internal network from an ECS instance, do not forbid access from VIP ranges described in the following table in the security group.
