Amazon MSK Connect Dual-Stack Connectivity

Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports dual-stack connectivity (IPv4 and IPv6) for new connectors on Amazon MSK Connect. This capability enables customers to create connectors on MSK Connect using both IPv4 and IPv6 protocols, in addition to the existing IPv4-only option. It helps customers modernize applications for IPv6 environments while maintaining IPv4 compatibility, making it easier to meet compliance requirements and prepare for future network architectures.

What to do

  • Enable dual-stack connectivity on new connectors using the Amazon MSK Console, AWS CLI, SDK, or CloudFormation by setting the Network Type parameter during connector creation.
  • All connectors on MSK Connect will by default use IPv4-only connectivity unless explicitly opted-in for dual-stack while creating new connectors.
  • Existing connectors will continue using IPv4 connectivity. To change that you will need to delete and recreate the connector.

Dual-stack connectivity for new connectors on MSK Connect is now available in all AWS Regions where Amazon MSK Connect is available, at no additional cost. To learn more about Amazon MSK dual-stack support, refer to the Amazon MSK developer guide.
