Amazon MemoryDB now supports Internet Protocol Version 6 (IPv6)

Amazon MemoryDB clusters now support the IPv6 protocol, allowing clients to connect to MemoryDB 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.

The continued growth of the internet is rapidly depleting available Internet Protocol version 4 (IPv4) addresses. By supporting IPv6, MemoryDB helps customers simplify their network architecture by providing a significantly larger address space and eliminating the need to manage overlapping address spaces in their VPCs. Customers can now standardize their applications on IPv6 and future-proof their infrastructure while maintaining compatibility with existing IPv4 systems through dual-stack support.

To get started, create your new MemoryDB 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 Valkey 7 and above, Redis OSS version 6.2 and above, in all AWS global regions and at no additional cost.
