Amazon ElastiCache clusters now support the IPv6 protocol, allowing clients to connect to ElastiCache clusters using IPv6. You can now configure your cluster to accept only IPv6 connections or to accept both IPv4 and IPv6 connections. This allows you to work to meet IPv6 compliance requirements and more efficiently integrate with existing IPv6-based applications.

To get started, create your new ElastiCache cluster using the Amazon Web Services Management Console, CLI, or SDKs and choose which protocol(s) it supports by setting its network type. IPv6 is supported when using Redis engine version 6.2 and above and Memcached version 1.6.6 and above, in all AWS global regions and at no additional cost. To learn more, see the documentation for Redis or the documentation for Memcached.
