Amazon Kinesis Data Streams expands Internet Protocol version 6 support to the AWS GovCloud (US) Regions

Posted on: Sep 18, 2025

Amazon Kinesis Data Streams now allows customers to make API requests over Internet Protocol version 6 (IPv6) in the AWS GovCloud (US) Regions. Customers have the option of using either IPv6 or IPv4 when sending requests over dual-stack public or VPC endpoints. The new endpoints have also been validated under the Federal Information Processing Standard (FIPS) 140-3 program.

Kinesis Data Streams allows users to capture, process, and store data streams in real time at any scale. IPv6 increases the number of available addresses by several orders of magnitude, so customers will no longer need to manage overlapping address spaces. Many devices and networks today already use IPv6, and now they can easily write to and read from data streams. FIPS-compliant endpoints help companies contracting with the US federal governments meet the FIPS security requirement to encrypt sensitive data in supported Regions.

Support for IPv6 with Kinesis Data Streams is now available in all Regions where Kinesis Data Streams is available, including AWS GovCloud (US) and China Regions. See here for a full listing of our Regions. To learn more about Kinesis Data Streams, please refer to our Developer Guide.
