Amazon MSK now supports dual-stack (IPv4 and IPv6) connectivity for existing clusters

Amazon MSK Dual-Stack Connectivity

Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports dual-stack connectivity (IPv4 and IPv6) for existing MSK Provisioned and MSK Serverless clusters. This new capability allows customers to connect to Amazon MSK using both IPv4 and IPv6 protocols, in addition to the existing IPv4-only option. This helps customers modernize applications for IPv6 environments while maintaining IPv4 compatibility.

Dual-stack connectivity can be enabled on existing MSK clusters by modifying the Network Type parameter from IPv4 to dual-stack using the Amazon MSK Console, AWS CLI, SDK, or CloudFormation. MSK provisions IPv6-enabled network interfaces while maintaining existing IPv4 connectivity, ensuring uninterrupted service.

What to do

• Update the Network Type parameter for your MSK clusters to dual-stack to enable IPv6 connectivity.
• Use the GetBootstrapBrokers API to obtain the new IPv6 bootstrap broker strings for MSK Provisioned clusters.

Dual-stack connectivity is available in all AWS Regions where Amazon MSK is available, at no additional cost.
