# How to access CDC stream endpoints in Amazon Keyspaces
<a name="CDC_access-endpoints"></a>

Amazon Keyspaces maintains separate  for keyspaces/tables and for CDC streams in each Amazon Web Services Region where Amazon Keyspaces is available. To access a CDC stream, select the Region of the table and replace the `cassandra` prefix with `cassandra-streams` in the endpoint name as shown in the following example:


| Region name | Region | Endpoint for keyspaces and tables | Endpoint for streams | 
| --- | --- | --- | --- | 
| US East (N. Virginia) | us-east-1 | {{cassandra}}.us-east-1.api.aws | {{cassandra-streams}}.us-east-1.api.aws | 

The following table contains a complete list of available public endpoints for Amazon Keyspaces change data capture streams. Amazon Keyspaces CDC streams supports both IPv4 and IPv6. All public endpoints, for example `cassandra-streams.us-east-1.api.aws`, are dual stack endpoints that can be configured for IPv4 and IPv6.
