Object Storage Service (OSS) data centers are located in regions. Endpoints are the domain names that other services can use to access OSS. This topic describes the mappings between regions and endpoints.
Regions and OSS endpoints in the public cloud
When you use internal endpoints of OSS, you must use the internal DNS addresses of Alibaba Cloud (100.100.2.136 and 100.100.2.138). Otherwise, you may not be able to obtain valid VIPs of the internal endpoints. As a result, access to OSS fails.
The following table describes the public endpoints and internal endpoints of OSS in each region in the public cloud.
Region | Region ID | Public endpoint | Internal endpoint |
China (Hangzhou) | oss-cn-hangzhou | oss-cn-hangzhou.aliyuncs.com Note By default, the | oss-cn-hangzhou-internal.aliyuncs.com Note By default, the oss-internal.aliyuncs.com endpoint maps to the internal endpoint of the China (Hangzhou) region. |

If you want to access OSS from other Alibaba Cloud services in the same region as OSS, we recommend that you use internal endpoints. For example, if you want to access an OSS bucket from an Elastic Compute Service (ECS) instance that resides in the same region as the OSS bucket, see Access to OSS resources from an ECS instance by using an internal endpoint of OSS for more details.
The names of the regions outside the Chinese mainland that are marked with ① are slightly different from those of the regions on the OSS pricing page or buy page. However, they all represent the same regions. For example, US-West-1 and US-West indicate the US (Silicon Valley) region. For more information, visit the OSS pricing page or OSS Resource Plan buy page.
Acceleration endpoints
If transfer acceleration is enabled for a bucket, the following acceleration endpoints are available:
Global acceleration endpoint:
oss-accelerate.aliyuncs.com
. Acceleration endpoints are distributed across the world. You can use a global acceleration endpoint to accelerate data transfer for buckets in all regions.Acceleration endpoint of regions outside the Chinese mainland:
oss-accelerate-overseas.aliyuncs.com
. Acceleration endpoints are distributed across regions outside the Chinese mainland. You can also use an acceleration endpoint together with a mapped custom domain name without an ICP filing to accelerate access to a bucket in the China (Hong Kong) region or in another region outside the Chinese mainland.
For more information, see Transfer acceleration.

Dual-stack endpoints are provided in some regions. A dual-stack endpoint allows an IPv4 client and an IPv6 client to access a bucket by using the same endpoint. For more information about the endpoints that support IPv6, see Use an endpoint that supports IPv6 to access OSS.
