OSS data centers are located in regions. Endpoints are the domain names that the other services can use to access OSS. This topic describes the mappings between regions and endpoints.
Regions and OSS endpoints for access over the classic network
Access over HTTPS is allowed in the classic network. The following table describes the public and internal endpoints of OSS in each region for access over the classic network.
| Region | Region ID | Public endpoint | Internal endpoint for access from ECS1 | Accelerate endpoint2 |

Note
- 1ECS instances can use internal endpoints to communicate with OSS only when the ECS instances and buckets are in the same region.
- 2Transfer acceleration endpoints include global accelerate endpoints and accelerate endpoints outside mainland China. Accelerate endpoints take effect after transfer acceleration is enabled. For more information, see Transfer acceleration.
- We recommend that you use third-level domains that are in the
Bucket+Endpointformat to share links or bind custom domain names (CNAME). For example, the third-level domain for the oss-sample bucket in the China (Shanghai) region isoss-sample.oss-cn-shanghai.aliyuncs.com. - When you initialize endpoints for OSS SDKs, we recommend that you specify the parameter
in the following format:
http(s)://+Endpoint. For example, we recommend that you set the initialization parameter tohttp://oss-cn-shanghai.aliyuncs.comorhttps://oss-cn-shanghai.aliyuncs.comfor the endpoint of the China (Shanghai) region, instead of thehttp://bucket.oss-cn-shanghai.aliyuncs.comthird-level domain. - By default, the
oss.aliyuncs.comendpoint maps to the public endpoint of the China (Hangzhou) region, and theoss-internal.aliyuncs.comendpoint maps to the internal endpoint of the China (Hangzhou) region.
Regions and OSS endpoints in VPCs
Access over HTTPS is allowed in VPCs. You can use the following endpoints to access
OSS from an ECS instance in the same region.
Notice When you access OSS internal endpoints by using Cloud Enterprise Network (CEN), Express
Connect, leased lines, or VPN, you must configure routes for network products. OSS
divides internal VIP address ranges for each region into fixed address ranges. When
you configure routes based on regions, you must configure complete four or six Class
C IP address ranges as listed in the following table.
| Region | Region ID | Endpoint in VPCs | VIP address range |

Use endpoints
- For more information about the composition rules of OSS domain names and how to access OSS over the internal network and Internet, see OSS domain names.
- If you need to access OSS by using an OSS internal endpoint from an ECS instance in the same region, see Access to OSS resources from ECS instances by using the internal endpoint of OSS.
