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.
By default, the
By default, the oss-internal.aliyuncs.com endpoint maps to the internal endpoint of the China (Hangzhou) region.
China (Nanjing - Local Region)
China (Hong Kong)
US (Silicon Valley) ①
US (Virginia) ①
Japan (Tokyo) ①
South Korea (Seoul)
Australia (Sydney) ①
Malaysia (Kuala Lumpur) ①
Indonesia (Jakarta) ①
India (Mumbai) ①
Germany (Frankfurt) ①
UAE (Dubai) ①
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 ECS instance that resides in the same region as the OSS bucket, see Access to OSS resources from ECS instances 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 region. 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.
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 use an acceleration endpoint to map a custom domain name without an ICP filing to a bucket in the China (Hong Kong) region or in another region outside the Chinese mainland.
For more information, see Enable transfer acceleration.

For more information about the comparison between internal endpoints and VIP ranges, see Internal endpoints of OSS buckets and VIP ranges.
Dual-stack endpoints are provided in some regions. This allows you to access a bucket by using an IPv4 or IPv6 client. For more information about the endpoints that support IPv6, see OSS domain names.
