# Allowed Domains
<a name="allowed-domains"></a>

**Important**  
The WorkSpaces Pools feature is not available in the Beijing and Ningxia Regions.

For WorkSpaces Pools users to access WorkSpaces, you must allow various domains on the network from which users initiate access to the WorkSpaces. For more information, see [IP address and port requirements for WorkSpaces Personal](workspaces-port-requirements.md). Note that the page specifies that it applies to WorkSpaces Personal but it also applies to WorkSpaces Pools.

**Note**  
If your S3 bucket has a “.” character in the name, the domain used is `https://s3.{{<aws-region>}}.amazonaws.com`. If your S3 bucket does not have a “.” character in the name, the domain used is `https://{{<bucket-name>}}.s3.{{<aws-region>}}.amazonaws.com`.
