IPv6 addressing with Amazon Redshift
Big Data Blog
This article explains how to migrate Amazon Redshift Serverless workgroups from IPv4-only to dual-stack (IPv4 and IPv6) networking mode.
- Dual-stack networking enables Redshift workgroups to communicate using both IPv4 and IPv6 protocols simultaneously
- New `ipAddressType` API field allows direct control over workgroup network configuration
- Dual-stack databases must operate in private subnets with VPC endpoints; IPv6-only and public dual-stack not supported
- Enable IPv6 CIDR blocks on VPC subnets before migrating Redshift workgroups
- Use AWS Console or CLI to enable dual-stack mode on existing Redshift Serverless workgroups
- Connection endpoints remain unchanged; existing IPv4 connections continue working
- Test connectivity from both IPv4 and IPv6-enabled EC2 instances using psql client
Migrating to dual-stack mode future-proofs Redshift environments while maintaining IPv4 compatibility during the gradual IPv4-to-IPv6 transition.
