Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

MemoryDB and IPV6

You can create new dual stack and ipv6-only clusters with both Valkey and Redis OSS engines, by providing subnet groups with dual stack and ipv6-only subnets. You cannot change the network type for an existing cluster.

With this functionality you can:

  • Create ipv4-only and dual stack clusters on dual stack subnets.

  • Create ipv6-only clusters on ipv6-only subnets.

  • Create new subnet groups to support ipv4-only, dual stack, and ipv6-only subnets.

  • Modify existing subnet groups to include additional subnets from the underlying VPC.

  • Modify existing subnets in subnet groups

    • Add IPv6 only subnets to subnet groups configured for IPv6

    • Add IPv4 or dual stack subnets to subnet groups configured for IPv4 and dual stack support

  • Discover all the nodes in the cluster with ipv4 OR ipv6 addresses, through engine discovery commands for dual stack and ipv6 clusters. These discovery commands include redis_info, redis_cluster, and similar.

  • Discover the ipv4 and ipv6 addresses of all the nodes in the cluster, through DNS discovery commands for dual stack and ipv6 clusters.
